+#######################
+Bond / Link Aggregation
+#######################
+
+The bonding interface provides a method for aggregating multiple network
+interfaces into a single logical "bonded" interface, or LAG, or ether-channel,
+or port-channel. The behavior of the bonded interfaces depends upon the mode;
+generally speaking, modes provide either hot standby or load balancing services.
+Additionally, link integrity monitoring may be performed.
+
+*************
+Configuration
+*************
+
+Common interface configuration
+==============================
+
+.. cmdinclude:: ../_include/interface-common-with-dhcp.txt
+   :var0: bond
+   :var1: bond0
+
+Member Interfaces
+=================
+
+.. cfgcmd:: set interfaces bonding <interface> member interface <member>
+
+   Enslave `<member>` interface to bond `<interface>`.
+
+Bond options
+============
+
+.. cfgcmd:: set interfaces bonding <interface> mode <802.3ad | active-backup |
+  broadcast | round-robin | transmit-load-balance | adaptive-load-balance |
+  xor-hash>
+
+   Specifies one of the bonding policies. The default is 802.3ad. Possible
+   values are:
+
+   * ``802.3ad`` - IEEE 802.3ad Dynamic link aggregation. Creates aggregation
+     groups that share the same speed and duplex settings. Utilizes all slaves
+     in the active aggregator according to the 802.3ad specification.
+
+     Slave selection for outgoing traffic is done according to the transmit
+     hash policy, which may be changed from the default simple XOR policy via
+     the :cfgcmd:`hash-policy` option, documented below.
+
+     .. note:: Not all transmit policies may be 802.3ad compliant, particularly
+        in regards to the packet mis-ordering requirements of section 43.2.4
+        of the 802.3ad standard.
+
+   * ``active-backup`` - Active-backup policy: Only one slave in the bond is
+     active. A different slave becomes active if, and only if, the active slave
+     fails. The bond's MAC address is externally visible on only one port
+     (network adapter) to avoid confusing the switch.
+
+     When a failover occurs in active-backup mode, bonding will issue one or
+     more gratuitous ARPs on the newly active slave. One gratuitous ARP is
+     issued for the bonding master interface and each VLAN interfaces
+     configured above it, provided that the interface has at least one IP
+     address configured. Gratuitous ARPs issued for VLAN interfaces are tagged
+     with the appropriate VLAN id.
+
+     This mode provides fault tolerance. The :cfgcmd:`primary` option,
+     documented below, affects the behavior of this mode.
+
+   * ``broadcast`` - Broadcast policy: transmits everything on all slave
+     interfaces.
+
+     This mode provides fault tolerance.
+
+   * ``round-robin`` - Round-robin policy: Transmit packets in sequential
+     order from the first available slave through the last.
+
+     This mode provides load balancing and fault tolerance.
+
+   * ``transmit-load-balance`` - Adaptive transmit load balancing: channel
+     bonding that does not require any special switch support.
+
+     Incoming traffic is received by the current slave. If the receiving slave
+     fails, another slave takes over the MAC address of the failed receiving
+     slave.
+
+   * ``adaptive-load-balance`` - Adaptive load balancing: includes
+     transmit-load-balance plus receive load balancing for IPV4 traffic, and
+     does not require any special switch support. The receive load balancing
+     is achieved by ARP negotiation. The bonding driver intercepts the ARP
+     Replies sent by the local system on their way out and overwrites the
+     source hardware address with the unique hardware address of one of the
+     slaves in the bond such that different peers use different hardware
+     addresses for the server.
+
+     Receive traffic from connections created by the server is also balanced.
+     When the local system sends an ARP Request the bonding driver copies and
+     saves the peer's IP information from the ARP packet. When the ARP Reply
+     arrives from the peer, its hardware address is retrieved and the bonding
+     driver initiates an ARP reply to this peer assigning it to one of the
+     slaves in the bond. A problematic outcome of using ARP negotiation for
+     balancing is that each time that an ARP request is broadcast it uses the
+     hardware address of the bond. Hence, peers learn the hardware address
+     of the bond and the balancing of receive traffic collapses to the current
+     slave. This is handled by sending updates (ARP Replies) to all the peers
+     with their individually assigned hardware address such that the traffic
+     is redistributed. Receive traffic is also redistributed when a new slave
+     is added to the bond and when an inactive slave is re-activated. The
+     receive load is distributed sequentially (round robin) among the group
+     of highest speed slaves in the bond.
+
+     When a link is reconnected or a new slave joins the bond the receive
+     traffic is redistributed among all active slaves in the bond by initiating
+     ARP Replies with the selected MAC address to each of the clients. The
+     updelay parameter (detailed below) must be set to a value equal or greater
+     than the switch's forwarding delay so that the ARP Replies sent to the
+     peers will not be blocked by the switch.
+
+   * ``xor-hash`` - XOR policy: Transmit based on the selected transmit
+     hash policy.  The default policy is a simple [(source MAC address XOR'd
+     with destination MAC address XOR packet type ID) modulo slave count].
+     Alternate transmit policies may be selected via the :cfgcmd:`hash-policy`
+     option, described below.
+
+     This mode provides load balancing and fault tolerance.
+
+.. cfgcmd:: set interfaces bonding <interface> min-links <0-16>
+
+   Specifies the minimum number of links that must be active before asserting
+   carrier. It is similar to the Cisco EtherChannel min-links feature. This
+   allows setting the minimum number of member ports that must be up (link-up
+   state) before marking the bond device as up (carrier on). This is useful for
+   situations where higher level services such as clustering want to ensure a
+   minimum number of low bandwidth links are active before switchover.
+
+   This option only affects 802.3ad mode.
+
+   The default value is 0. This will cause carrier to be asserted (for 802.3ad
+   mode) whenever there is an active aggregator, regardless of the number of
+   available links in that aggregator.
+
+   .. note:: Because an aggregator cannot be active without at least one
+      available link, setting this option to 0 or to 1 has the exact same
+      effect.
+
+.. cfgcmd:: set interfaces bonding <interface> hash-policy <policy>
+
+   * **layer2** - Uses XOR of hardware MAC addresses and packet type ID field
+     to generate the hash. The formula is
+
+     .. code-block:: none
+
+       hash = source MAC XOR destination MAC XOR packet type ID
+       slave number = hash modulo slave count
+
+     This algorithm will place all traffic to a particular network peer on
+     the same slave.
+
+     This algorithm is 802.3ad compliant.
+
+   * **layer2+3** - This policy uses a combination of layer2 and layer3
+     protocol information to generate the hash. Uses XOR of hardware MAC
+     addresses and IP addresses to generate the hash. The formula is:
+
+     .. code-block:: none
+
+       hash = source MAC XOR destination MAC XOR packet type ID
+       hash = hash XOR source IP XOR destination IP
+       hash = hash XOR (hash RSHIFT 16)
+       hash = hash XOR (hash RSHIFT 8)
+
+     And then hash is reduced modulo slave count.
+
+     If the protocol is IPv6 then the source and destination addresses are
+     first hashed using ipv6_addr_hash.
+
+     This algorithm will place all traffic to a particular network peer on the
+     same slave. For non-IP traffic, the formula is the same as for the layer2
+     transmit hash policy.
+
+     This policy is intended to provide a more balanced distribution of traffic
+     than layer2 alone, especially in environments where a layer3 gateway
+     device is required to reach most destinations.
+
+     This algorithm is 802.3ad compliant.
+
+   * **layer3+4** - This policy uses upper layer protocol information, when
+     available, to generate the hash. This allows for traffic to a particular
+     network peer to span multiple slaves, although a single connection will
+     not span multiple slaves.
+
+     The formula for unfragmented TCP and UDP packets is
+
+     .. code-block:: none
+
+       hash = source port, destination port (as in the header)
+       hash = hash XOR source IP XOR destination IP
+       hash = hash XOR (hash RSHIFT 16)
+       hash = hash XOR (hash RSHIFT 8)
+
+     And then hash is reduced modulo slave count.
+
+     If the protocol is IPv6 then the source and destination addresses are
+     first hashed using ipv6_addr_hash.
+
+     For fragmented TCP or UDP packets and all other IPv4 and IPv6 protocol
+     traffic, the source and destination port information is omitted. For
+     non-IP traffic, the formula is the same as for the layer2 transmit hash
+     policy.
+
+     This algorithm is not fully 802.3ad compliant. A single TCP or UDP
+     conversation containing both fragmented and unfragmented packets will see
+     packets striped across two interfaces. This may result in out of order
+     delivery. Most traffic types will not meet this criteria, as TCP rarely
+     fragments traffic, and most UDP traffic is not involved in extended
+     conversations. Other implementations of 802.3ad may or may not tolerate
+     this noncompliance.
+
+.. cfgcmd:: set interfaces bonding <interface> primary <interface>
+
+    An `<interface>` specifying which slave is the primary device. The specified
+    device will always be the active slave while it is available. Only when the
+    primary is off-line will alternate devices be used. This is useful when one
+    slave is preferred over another, e.g., when one slave has higher throughput
+    than another.
+
+    The primary option is only valid for active-backup, transmit-load-balance,
+    and adaptive-load-balance mode.
+
+.. cfgcmd:: set interfaces bonding <interface> arp-monitor interval <time>
+
+   Specifies the ARP link monitoring `<time>` in seconds.
+
+   The ARP monitor works by periodically checking the slave devices to determine
+   whether they have sent or received traffic recently (the precise criteria
+   depends upon the bonding mode, and the state of the slave). Regular traffic
+   is generated via ARP probes issued for the addresses specified by the
+   :cfgcmd:`arp-monitor target` option.
+
+   If ARP monitoring is used in an etherchannel compatible mode (modes
+   round-robin and xor-hash), the switch should be configured in a mode that
+   evenly distributes packets across all links. If the switch is configured to
+   distribute the packets in an XOR fashion, all replies from the ARP targets
+   will be received on the same link which could cause the other team members
+   to fail.
+
+   A value of 0 disables ARP monitoring. The default value is 0.
+
+.. cfgcmd:: set interfaces bonding <interface> arp-monitor target <address>
+
+   Specifies the IP addresses to use as ARP monitoring peers when
+   :cfgcmd:`arp-monitor interval` option is > 0. These are the targets of the
+   ARP request sent to determine the health of the link to the targets.
+
+   Multiple target IP addresses can be specified. At least one IP address must
+   be given for ARP monitoring to function.
+
+   The maximum number of targets that can be specified is 16. The default value
+   is no IP addresses.

+Bridge
+######
+
+A Bridge is a way to connect two Ethernet segments together in a
+protocol independent way. Packets are forwarded based on Ethernet
+address, rather than IP address (like a router). Since forwarding is
+done at Layer 2, all protocols can go transparently through a bridge.
+The Linux bridge code implements a subset of the ANSI/IEEE 802.1d
+standard.
+
+.. note:: Spanning Tree Protocol is not enabled by default in VyOS.
+   :ref:`stp` can be easily enabled if needed.
+
+*************
+Configuration
+*************
+
+Common interface configuration
+==============================
+
+.. cmdinclude:: ../_include/interface-common-with-dhcp.txt
+   :var0: bridge
+   :var1: br0
+
+Member Interfaces
+=================
+
+.. cfgcmd:: set interfaces bridge <interface> member interface <member>
+
+   Assign `<member>` interface to bridge `<interface>`. A completion
+   helper will help you with all allowed interfaces which can be
+   bridged. This includes :ref:`ethernet-interface`,
+   :ref:`bond-interface`, :ref:`l2tpv3-interface`, :ref:`openvpn`,
+   :ref:`vxlan-interface`, :ref:`wireless-interface`,
+   :ref:`tunnel-interface` and :ref:`geneve-interface`.
+
+
+.. cfgcmd:: set interfaces bridge <interface> member interface <member>
+   priority <priority>
+
+   Configure individual bridge port `<priority>`.
+
+   Each bridge has a relative priority and cost. Each interface is
+   associated with a port (number) in the STP code. Each has a priority
+   and a cost, that is used to decide which is the shortest path to
+   forward a packet. The lowest cost path is always used unless the
+   other path is down. If you have multiple bridges and interfaces then
+   you may need to adjust the priorities to achieve optimium
+   performance.
+
+
+.. cfgcmd:: set interfaces bridge <interface> member interface <member>
+   cost <cost>
+
+   Path `<cost>` value for Spanning Tree Protocol. Each interface in a
+   bridge could have a different speed and this value is used when
+   deciding which link to use. Faster interfaces should have lower
+   costs.
+
+Bridge Options
+==============
+
+.. cfgcmd:: set interfaces bridge <interface> aging <time>
+
+   MAC address aging `<time`> in seconds (default: 300).
+
+.. cfgcmd:: set interfaces bridge <interface> max-age <time>
+
+   Bridge maximum aging `<time>` in seconds (default: 20).
+
+   If a another bridge in the spanning tree does not send out a hello
+   packet for a long period of time, it is assumed to be dead.
+
+.. cfgcmd:: set interfaces bridge <interface> igmp querier
+
+   Enable IGMP querier
+
+.. _stp:
+
+STP Parameter
+-------------
+
+:abbr:`STP (Spanning Tree Protocol)` is a network protocol that builds a
+loop-free logical topology for Ethernet networks. The basic function of
+STP is to prevent bridge loops and the broadcast radiation that results
+from them. Spanning tree also allows a network design to include backup
+links providing fault tolerance if an active link fails.
+
+.. cfgcmd:: set interfaces bridge <interface> stp
+
+   Enable spanning tree protocol. STP is disabled by default.
+
+
+.. cfgcmd:: set interfaces bridge <interface> forwarding-delay <delay>
+
+   Spanning Tree Protocol forwarding `<delay>` in seconds (default: 15).
+
+   Forwarding delay time is the time spent in each of the Listening and
+   Learning states before the Forwarding state is entered. This delay is
+   so that when a new bridge comes onto a busy network it looks at some
+   traffic before participating.
+
+
+.. cfgcmd:: set interfaces bridge <interface> hello-time <interval>
+
+   Spanning Tree Protocol hello advertisement `<interval>` in seconds
+   (default: 2).
+
+   Periodically, a hello packet is sent out by the Root Bridge and the
+   Designated Bridges. Hello packets are used to communicate information
+   about the topology throughout the entire Bridged Local Area Network.
+
+VLAN
+====
+
+.. cmdinclude:: ../_include/interface-vlan-8021q.txt
+   :var0: bridge
+   :var1: br0
+
+.. cfgcmd:: set interfaces bridge <interface> member interface <member>
+   native-vlan <vlan-id>
+
+   Set the native VLAN ID flag of the interface. When a data packet without a
+   VLAN tag enters the port, the data packet will be forced to add a tag of a
+   specific vlan id. When the vlan id flag flows out, the tag of the vlan id
+   will be stripped
+
+.. cfgcmd:: set interfaces bridge <interface> member interface <member>
+   allowed-vlan <vlan-id>
+
+   Allows specific VLAN IDs to pass through the bridge member interface. This
+   can either be an individual VLAN id or a range of VLAN ids delimited by a
+   hyphen.
+
+*******
+Example
+*******
+
+Creating a bridge interface is very simple. In this example we will
+have:
+
+* A bridge named `br100`
+* Member interfaces `eth1` and VLAN 10 on interface `eth2`
+* Enable STP
+* Bridge answers on IP address 192.0.2.1/24 and 2001:db8::ffff/64
+
+.. code-block:: none
+
+  set interfaces bridge br100 address 192.0.2.1/24
+  set interfaces bridge br100 address 2001:db8::ffff/64
+  set interfaces bridge br100 member interface eth1
+  set interfaces bridge br100 member interface eth2.10
+  set interfaces bridge br100 stp
+
+This results in the active configuration:
+
+.. code-block:: none
+
+   vyos@vyos# show interfaces bridge br100
+    address 192.0.2.1/24
+    address 2001:db8::ffff/64
+    member {
+        interface eth1 {
+        }
+        interface eth2.10 {
+        }
+    }
+    stp
+
+*******
+Example
+*******
+
+An example of creating a VLAN-aware bridge is as follows:
+
+* A bridge named `br100`
+* The member interface `eth1` is a trunk that allows VLAN 10 to pass
+* VLAN 10 on member interface `eth2` (ACCESS mode)
+* Enable STP
+* Bridge answers on IP address 192.0.2.1/24 and 2001:db8::ffff/64
+
+.. code-block:: none
+
+  set interfaces bridge br100 member interface eth1 allowed-vlan 10
+  set interfaces bridge br100 member interface eth2 native-vlan 10
+  set interfaces bridge br100 vif 10 address 192.0.2.1/24
+  set interfaces bridge br100 vif 10 address 2001:db8::ffff/64
+  set interfaces bridge br100 stp
+
+This results in the active configuration:
+
+.. code-block:: none
+
+   vyos@vyos# show interfaces bridge br100
+    member {
+        interface eth1 {
+            allowed-vlan 10
+        }
+        interface eth2 {
+            native-vlan 10
+        }
+    }
+    stp
+    vif 10 {
+        address 192.0.2.1/24
+        address 2001:db8::ffff/64
+    }

+Dummy
+#####
+
+The dummy interface is really a little exotic, but rather useful nevertheless.
+Dummy interfaces are much like the :ref:`loopback-interface` interface, except
+you can have as many as you want.
+
+.. note:: Dummy interfaces can be used as interfaces that always stay up (in
+   the same fashion to loopbacks in Cisco IOS), or for testing purposes.
+
+.. hint:: A Dummy interface is always up, thus it could be used for
+   management traffic or as source/destination for and :abbr:`IGP (Interior
+   Gateway Protocol)` like :ref:`bgp` so your internal BGP link is not dependent
+   on physical link states and multiple routes can be chosen to the
+   destination. A :ref:`dummy-interface` Interface should always be preferred
+   over a :ref:`loopback-interface` interface.

+the capabilities of :abbr:`VXLAN (Virtual Extensible LAN)`, :abbr:`NVGRE
+(Network Virtualization using Generic Routing Encapsulation)`, and :abbr:`STT
+(Stateless Transport Tunneling)` and was designed to overcome their perceived

+entirely.
+
+GENEVE is designed to support network virtualization use cases, where tunnels
+are typically established to act as a backplane between the virtual switches
+residing in hypervisors, physical switches, or middleboxes or other appliances.
+An arbitrary IP network can be used as an underlay although Clos networks - A
+technique for composing network fabrics larger than a single switch while
+maintaining non-blocking bandwidth across connection points. ECMP is used to
+divide traffic across the multiple links and switches that constitute the
+fabric. Sometimes termed "leaf and spine" or "fat tree" topologies.

+L2TPv3
+######
+
+Layer 2 Tunnelling Protocol Version 3 is an IETF standard related to L2TP that
+can be used as an alternative protocol to :ref:`mpls` for encapsulation of
+multiprotocol Layer 2 communications traffic over IP networks. Like L2TP,
+L2TPv3 provides a pseudo-wire service, but scaled to fit carrier requirements.
+
+L2TPv3 can be regarded as being to MPLS what IP is to ATM: a simplified version
+of the same concept, with much of the same benefit achieved at a fraction of the
+effort, at the cost of losing some technical features considered less important
+in the market.
+
+In the case of L2TPv3, the features lost are teletraffic engineering features
+considered important in MPLS. However, there is no reason these features could
+not be re-engineered in or on top of L2TPv3 in later products.
+
+The protocol overhead of L2TPv3 is also significantly bigger than MPLS.
+
+L2TPv3 is described in :rfc:`3921`.

+
+Over IP
+=======
+
+.. code-block:: none
+
+  # show interfaces l2tpv3
+  l2tpv3 l2tpeth10 {
+      address 192.168.37.1/27
+      encapsulation ip
+      local-ip 192.0.2.1
+      peer-session-id 100
+      peer-tunnel-id 200
+      remote-ip 203.0.113.24
+      session-id 100
+      tunnel-id 200
+  }
+
+Inverse configuration has to be applied to the remote side.
+
+Over UDP
+========
+
+UDP mode works better with NAT:
+
+* Set local-ip to your local IP (LAN).
+* Add a forwarding rule matching UDP port on your internet router.
+
+.. code-block:: none
+
+  # show interfaces l2tpv3
+  l2tpv3 l2tpeth10 {
+      address 192.168.37.1/27
+      destination-port 9001
+      encapsulation udp
+      local-ip 192.0.2.1
+      peer-session-id 100
+      peer-tunnel-id 200
+      remote-ip 203.0.113.24
+      session-id 100
+      source-port 9000
+      tunnel-id 200
+  }
+
+To create more than one tunnel, use distinct UDP ports.
+

+MACsec
+######
+
+MACsec is an IEEE standard (IEEE 802.1AE) for MAC security, introduced in 2006.
+It defines a way to establish a protocol independent connection between two
+hosts with data confidentiality, authenticity and/or integrity, using
+GCM-AES-128. MACsec operates on the Ethernet layer and as such is a layer 2
+protocol, which means it's designed to secure traffic within a layer 2 network,
+including DHCP or ARP requests. It does not compete with other security
+solutions such as IPsec (layer 3) or TLS (layer 4), as all those solutions are
+used for their own specific use cases.

+OpenVPN
+#######
+
+Traditionally hardware routers implement IPsec exclusively due to relative
+ease of implementing it in hardware and insufficient CPU power for doing
+encryption in software. Since VyOS is a software router, this is less of a
+concern. OpenVPN has been widely used on UNIX platform for a long time and is
+a popular option for remote access VPN, though it's also capable of
+site-to-site connections.
+
+Advantages of OpenVPN are:
+
+* It uses a single TCP or UDP connection and does not rely on packet source
+  addresses, so it will work even through a double NAT: perfect for public
+  hotspots and such
+
+* It's easy to setup and offers very flexible split tunneling
+
+* There's a variety of client GUI frontends for any platform
+
+Disadvantages are:
+
+* It's slower than IPsec due to higher protocol overhead and the fact it runs
+  in user mode while IPsec, on Linux, is in kernel mode
+
+* None of the operating systems have client software installed by default
+
+In the VyOS CLI, a key point often overlooked is that rather than being
+configured using the `set vpn` stanza, OpenVPN is configured as a network
+interface using `set interfaces openvpn`.
+
+Site-To-Site
+============
+
+While many are aware of OpenVPN as a Client VPN solution, it is often
+overlooked as a site-to-site VPN solution due to lack of support for this mode
+in many router platforms.
+
+Site-to-site mode supports x.509 but doesn't require it and can also work with
+static keys, which is simpler in many cases. In this example, we'll configure
+a simple site-to-site OpenVPN tunnel using a 2048-bit pre-shared key.
+
+First, one of the systems generate the key using the operational command
+``generate openvpn key <filename>``. This will generate a key with the name
+provided in the ``/config/auth/`` directory. Once generated, you will need to
+copy this key to the remote router.
+
+In our example, we used the filename ``openvpn-1.key`` which we will reference
+in our configuration.
+
+* The public IP address of the local side of the VPN will be 198.51.100.10
+* The remote will be 203.0.113.11
+* The tunnel will use 10.255.1.1 for the local IP and 10.255.1.2 for the remote.
+* OpenVPN allows for either TCP or UDP. UDP will provide the lowest latency,
+  while TCP will work better for lossy connections; generally UDP is preferred
+  when possible.
+* The official port for OpenVPN is 1194, which we reserve for client VPN; we
+  will use 1195 for site-to-site VPN.
+* The ``persistent-tunnel`` directive will allow us to configure tunnel-related
+  attributes, such as firewall policy as we would on any normal network
+  interface.
+* If known, the IP of the remote router can be configured using the
+  ``remote-host`` directive; if unknown, it can be omitted. We will assume a
+  dynamic IP for our remote router.
+
+Local Configuration:
+
+.. code-block:: none
+
+  set interfaces openvpn vtun1 mode site-to-site
+  set interfaces openvpn vtun1 protocol udp
+  set interfaces openvpn vtun1 persistent-tunnel
+  set interfaces openvpn vtun1 local-host '198.51.100.10'
+  set interfaces openvpn vtun1 local-port '1195'
+  set interfaces openvpn vtun1 remote-port '1195'
+  set interfaces openvpn vtun1 shared-secret-key-file '/config/auth/openvpn-1.key'
+  set interfaces openvpn vtun1 local-address '10.255.1.1'
+  set interfaces openvpn vtun1 remote-address '10.255.1.2'
+
+Remote Configuration:
+
+.. code-block:: none
+
+  set interfaces openvpn vtun1 mode site-to-site
+  set interfaces openvpn vtun1 protocol udp
+  set interfaces openvpn vtun1 persistent-tunnel
+  set interfaces openvpn vtun1 remote-host '198.51.100.10'
+  set interfaces openvpn vtun1 local-port '1195'
+  set interfaces openvpn vtun1 remote-port '1195'
+  set interfaces openvpn vtun1 shared-secret-key-file '/config/auth/openvpn-1.key'
+  set interfaces openvpn vtun1 local-address '10.255.1.2'
+  set interfaces openvpn vtun1 remote-address '10.255.1.1'
+
+The configurations above will default to using 256-bit AES in GCM mode
+for encryption (if both sides supports NCP) and SHA-1 for HMAC authentication.
+SHA-1 is considered weak, but other hashing algorithms are available, as are
+encryption algorithms:
+
+For Encryption:
+
+This sets the cipher when NCP (Negotiable Crypto Parameters) is disabled or
+OpenVPN version < 2.4.0.
+
+.. code-block:: none
+
+  vyos@vyos# set interfaces openvpn vtun1 encryption cipher
+  Possible completions:
+    des          DES algorithm
+    3des         DES algorithm with triple encryption
+    bf128        Blowfish algorithm with 128-bit key
+    bf256        Blowfish algorithm with 256-bit key
+    aes128       AES algorithm with 128-bit key CBC

+    aes256       AES algorithm with 256-bit key CBC
+    aes256gcm    AES algorithm with 256-bit key GCM
+
+This sets the accepted ciphers to use when version => 2.4.0 and NCP is
+enabled (which is default). Default NCP cipher for versions >= 2.4.0 is
+aes256gcm. The first cipher in this list is what server pushes to clients.
+

+    sha1         SHA-1 algorithm
+    sha256       SHA-256 algorithm
+    sha512       SHA-512 algorithm
+
+If you change the default encryption and hashing algorithms, be sure that the
+local and remote ends have matching configurations, otherwise the tunnel will
+not come up.
+
+Static routes can be configured referencing the tunnel interface; for example,
+the local router will use a network of 10.0.0.0/16, while the remote has a
+network of 10.1.0.0/16:
+
+Local Configuration:
+
+.. code-block:: none
+
+  set protocols static interface-route 10.1.0.0/16 next-hop-interface vtun1
+
+Remote Configuration:
+
+.. code-block:: none
+
+  set protocols static interface-route 10.0.0.0/16 next-hop-interface vtun1
+
+Firewall policy can also be applied to the tunnel interface for `local`, `in`,
+and `out` directions and function identically to ethernet interfaces.
+
+If making use of multiple tunnels, OpenVPN must have a way to distinguish
+between different tunnels aside from the pre-shared-key. This is either by
+referencing IP address or port number. One option is to dedicate a public IP
+to each tunnel. Another option is to dedicate a port number to each tunnel
+(e.g. 1195,1196,1197...).
+
+OpenVPN status can be verified using the `show openvpn` operational commands.
+See the built-in help for a complete list of options.
+
+Server
+======
+
+Multi-client server is the most popular OpenVPN mode on routers. It always uses
+x.509 authentication and therefore requires a PKI setup. Refer this section
+**Generate X.509 Certificate and Keys** to generate a CA certificate,
+a server certificate and key, a certificate revocation list, a Diffie-Hellman
+key exchange parameters file. You do not need client certificates and keys for the server setup.
+
+In this example we will use the most complicated case: a setup where each
+client is a router that has its own subnet (think HQ and branch offices), since
+simpler setups are subsets of it.
+
+Suppose you want to use 10.23.1.0/24 network for client tunnel endpoints and
+all client subnets belong to 10.23.0.0/20. All clients need access to the
+192.168.0.0/16 network.
+
+First we need to specify the basic settings. 1194/UDP is the default. The
+``persistent-tunnel`` option is recommended, it prevents the TUN/TAP device from
+closing on connection resets or daemon reloads.
+
+.. note:: Using **openvpn-option -reneg-sec** can be tricky. This option is
+   used to renegotiate data channel after n seconds. When used at both server
+   and client, the lower value will trigger the renegotiation. If you set it to
+   0 on one side of the connection (to disable it), the chosen value on the
+   other side will determine when the renegotiation will occur.
+
+.. code-block:: none
+
+  set interfaces openvpn vtun10 mode server
+  set interfaces openvpn vtun10 local-port 1194
+  set interfaces openvpn vtun10 persistent-tunnel
+  set interfaces openvpn vtun10 protocol udp
+
+Then we need to specify the location of the cryptographic materials. Suppose
+you keep the files in `/config/auth/openvpn`
+
+.. code-block:: none
+
+  set interfaces openvpn vtun10 tls ca-cert-file /config/auth/openvpn/ca.crt
+  set interfaces openvpn vtun10 tls cert-file /config/auth/openvpn/server.crt
+  set interfaces openvpn vtun10 tls key-file /config/auth/openvpn/server.key
+  set interfaces openvpn vtun10 tls crl-file /config/auth/openvpn/crl.pem
+  set interfaces openvpn vtun10 tls dh-file /config/auth/openvpn/dh2048.pem
+
+Now we need to specify the server network settings. In all cases we need to
+specify the subnet for client tunnel endpoints. Since we want clients to access
+a specific network behind out router, we will use a push-route option for
+installing that route on clients.
+
+.. code-block:: none
+
+  set interfaces openvpn vtun10 server push-route 192.168.0.0/16
+  set interfaces openvpn vtun10 server subnet 10.23.1.0/24
+
+Since it's a HQ and branch offices setup, we will want all clients to have
+fixed addresses and we will route traffic to specific subnets through them. We
+need configuration for each client to achieve this.
+
+.. note:: Clients are identified by the CN field of their x.509 certificates,
+   in this example the CN is ``client0``:
+
+.. code-block:: none
+
+  set interfaces openvpn vtun10 server client client0 ip 10.23.1.10
+  set interfaces openvpn vtun10 server client client0 subnet 10.23.2.0/25
+
+OpenVPN **will not** automatically create routes in the kernel for client
+subnets when they connect and will only use client-subnet association
+internally, so we need to create a route to the 10.23.0.0/20 network ourselves:
+
+.. code-block:: none
+
+  set protocols static interface-route 10.23.0.0/20 next-hop-interface vtun10
+
+Generate X.509 Certificate and Keys
+-----------------------------------
+
+OpenVPN ships with a set of scripts called Easy-RSA that can generate the
+appropriate files needed for an OpenVPN setup using X.509 certificates.
+Easy-RSA comes installed by default on VyOS routers.
+
+Copy the Easy-RSA scripts to a new directory to modify the values.
+
+.. code-block:: none
+
+  cp -r /usr/share/easy-rsa/ /config/my-easy-rsa-config
+  cd /config/my-easy-rsa-config
+
+To ensure the consistent use of values when generating the PKI, set default
+values to be used by the PKI generating scripts. Rename the vars.example filename
+to vars
+
+.. code-block:: none
+
+  mv vars.example vars
+
+Following is the instance of the file after editing. You may also change other values in
+the file at your discretion/need, though for most cases the defaults should be just fine.
+(do not leave any of these parameters blank)
+
+.. code-block:: none
+
+  set_var EASYRSA_DN      "org"
+  set_var EASYRSA_REQ_COUNTRY     "US"
+  set_var EASYRSA_REQ_PROVINCE    "California"
+  set_var EASYRSA_REQ_CITY        "San Francisco"
+  set_var EASYRSA_REQ_ORG "Copyleft Certificate Co"
+  set_var EASYRSA_REQ_EMAIL       "me@example.net"
+  set_var EASYRSA_REQ_OU          "My Organizational Unit"
+  set_var EASYRSA_KEY_SIZE        2048
+
+
+init-pki option will create a new pki directory or will delete any previously generated
+certificates stored in that folder. The term 'central' is used to refer server and
+'branch' for client
+
+.. note:: Remember the “CA Key Passphrase” prompted in build-ca command,
+   as it will be asked in signing the server/client certificate.
+
+.. code-block:: none

+  vyos@vyos:/config/my-easy-rsa-config$./easyrsa gen-dh
+  vyos@vyos:/config/my-easy-rsa-config$./easyrsa build-client-full branch1 nopass
+
+To generate a certificate revocation list for any client, execute these commands:
+
+.. code-block:: none
+
+  vyos@vyos:/config/my-easy-rsa-config$./easyrsa revoke client1
+  vyos@vyos:/config/my-easy-rsa-config$ ./easyrsa gen-crl
+
+Copy the files to /config/auth/ovpn/ to use in OpenVPN tunnel creation
+
+.. code-block:: none
+
+  vyos@vyos:/config/my-easy-rsa-config$ sudo mkdir /config/auth/ovpn
+  vyos@vyos:/config/my-easy-rsa-config$ sudo cp pki/ca.crt /config/auth/ovpn
+  vyos@vyos:/config/my-easy-rsa-config$ sudo cp pki/dh.pem  /config/auth/ovpn
+  vyos@vyos:/config/my-easy-rsa-config$ sudo cp pki/private/central.key /config/auth/ovpn
+  vyos@vyos:/config/my-easy-rsa-config$ sudo cp pki/issued/central.crt  /config/auth/ovpn
+  vyos@vyos:/config/my-easy-rsa-config$ sudo cp pki/crl.pem /config/auth/ovpn
+
+Additionally, each client needs a copy of ca.crt and its own client key and cert files.
+The files are plaintext so they may be copied either manually,
+or through a remote file transfer tool like scp. Whichever method you use,
+the files need to end up in the proper location on each router.
+For example, Branch 1's router might have the following files:
+
+.. code-block:: none
+
+  vyos@branch1-rtr:$ ls /config/auth/ovpn
+  ca.crt branch1.crt branch1.key
+
+Client Authentication
+=====================
+
+LDAP
+----
+
+Enterprise installations usually ship a kind of directory service which is used
+to have a single password store for all employees. VyOS and OpenVPN support using
+LDAP/AD as single user backend.
+
+Authentication is done by using the ``openvpn-auth-ldap.so`` plugin which is
+shipped with every VyOS installation. A dedicated configuration file is required.
+It is best practise to store it in ``/config`` to survive image updates
+
+.. code-block:: none
+
+  set interfaces openvpn vtun0 openvpn-option "--plugin /usr/lib/openvpn/openvpn-auth-ldap.so /config/auth/ldap-auth.config"
+
+The required config file may look like:
+
+.. code-block:: none
+
+  <LDAP>
+  # LDAP server URL
+  URL             ldap://ldap.example.com
+  # Bind DN (If your LDAP server doesn't support anonymous binds)
+  BindDN          cn=LDAPUser,dc=example,dc=com
+  # Bind Password password
+  Password        S3cr3t
+  # Network timeout (in seconds)
+  Timeout         15
+  </LDAP>
+
+  <Authorization>
+  # Base DN
+  BaseDN          "ou=people,dc=example,dc=com"
+  # User Search Filter
+  SearchFilter    "(&(uid=%u)(objectClass=shadowAccount))"
+  # Require Group Membership - allow all users
+  RequireGroup    false
+  </Authorization>
+
+Active Directory
+^^^^^^^^^^^^^^^^
+
+Despite the fact that AD is a superset of LDAP
+
+.. code-block:: none

+
+Client
+======
+
+VyOS can not only act as an OpenVPN site-to-site or Server for multiple clients.
+You can indeed also configure any VyOS OpenVPN interface as an OpenVPN client
+connecting to a VyOS OpenVPN server or any other OpenVPN server.
+
+Given the following example we have one VyOS router acting as OpenVPN server
+and another VyOS router acting as OpenVPN client. The Server also pushes a
+static client IP address to the OpenVPN client. Remember, clients are identified
+using their CN attribute in the SSL certificate.
+

+
+Options
+=======
+
+We do not have CLI nodes for every single OpenVPN options. If an option is
+missing, a feature request should be opened at Phabricator_ so all users can
+benefit from it (see :ref:`issues_features`).
+
+If you are a hacker or want to try on your own we support passing raw OpenVPN
+options to OpenVPN.
+
+.. cfgcmd:: set interfaces openvpn vtun10 openvpn-option 'persistent-key'
+
+Will add ``persistent-key`` at the end of the generated OpenVPN configuration.
+Please use this only as last resort - things might break and OpenVPN won't start
+if you pass invalid options/syntax.
+
+.. cfgcmd:: set interfaces openvpn vtun10 openvpn-option 'push &quot;keepalive 1 10&quot;'
+
+Will add ``push "keepalive 1 10"`` to the generated OpenVPN config file.
+
+.. note:: Sometimes option lines in the generated OpenVPN configurarion require
+   quotes. This is done through a hack on our config generator. You can pass
+   quotes using the ``&quot;`` statement.
+
+

+PPPoE
+#####
+
+:abbr:`PPPoE (Point-to-Point Protocol over Ethernet)` is a network protocol
+for encapsulating PPP frames inside Ethernet frames. It appeared in 1999,
+in the context of the boom of DSL as the solution for tunneling packets
+over the DSL connection to the :abbr:`ISPs (Internet Service Providers)`
+IP network, and from there to the rest of the Internet. A 2005 networking
+book noted that "Most DSL providers use PPPoE, which provides authentication,
+encryption, and compression." Typical use of PPPoE involves leveraging the
+PPP facilities for authenticating the user with a username and password,
+predominately via the PAP protocol and less often via CHAP.
+
+***************
+Operating Modes
+***************
+
+VyOS supports setting up PPPoE in two different ways to a PPPoE internet
+connection. This is due to most ISPs provide a modem that is also a wireless
+router.
+
+Home Users
+==========
+
+In this method, the DSL Modem/Router connects to the ISP for you with your
+credentials preprogrammed into the device. This gives you an :rfc:`1918`
+address, such as ``192.168.1.0/24`` by default.
+
+For a simple home network using just the ISP's equipment, this is usually
+desirable. But if you want to run VyOS as your firewall and router, this
+will result in having a double NAT and firewall setup. This results in a
+few extra layers of complexity, particularly if you use some NAT or
+tunnel features.
+
+Business Users
+==============
+
+In order to have full control and make use of multiple static public IP
+addresses, your VyOS will have to initiate the PPPoE connection and control
+it. In order for this method to work, you will have to figure out how to make
+your DSL Modem/Router switch into a Bridged Mode so it only acts as a DSL
+Transceiver device to connect between the Ethernet link of your VyOS and the
+phone cable. Once your DSL Transceiver is in Bridge Mode, you should get no
+IP address from it. Please make sure you connect to the Ethernet Port 1 if
+your DSL Transeiver has a switch, as some of them only work this way.
+
+Once you have an Ethernet device connected, i.e. `eth0`, then you can
+configure it to open the PPPoE session for you and your DSL Transceiver
+(Modem/Router) just acts to translate your messages in a way that
+vDSL/aDSL understands.

+
+PPPoE options
+=============
+
+.. cfgcmd:: set interfaces pppoe <interface> access-concentrator <name>
+
+   Use this command to restrict the PPPoE session on a given access
+   concentrator. Normally, a host sends a PPPoE initiation packet to start the
+   PPPoE discovery process, a number of access concentrators respond with offer
+   packets and the host selects one of the responding access concentrators to
+   serve this session.
+
+   This command allows you to select a specific access concentrator when you
+   know the access concentrators `<name>`.
+
+.. cfgcmd:: set interfaces pppoe <interface> authentication user <username>
+
+   Use this command to set the username for authenticating with a remote PPPoE
+   endpoint. Authentication is optional from the system's point of view but
+   most service providers require it.
+
+.. cfgcmd:: set interfaces pppoe <interface> authentication password <password>
+
+   Use this command to set the password for authenticating with a remote PPPoE
+   endpoint. Authentication is optional from the system's point of view but
+   most service providers require it.
+
+.. cfgcmd:: set interfaces pppoe <interface> connect-on-demand
+
+   When set the interface is enabled for "dial-on-demand".
+
+   Use this command to instruct the system to establish a PPPoE connections
+   automatically once traffic passes through the interface. A disabled on-demand
+   connection is established at boot time and remains up. If the link fails for
+   any reason, the link is brought back up immediately.
+
+   Enabled on-demand PPPoE connections bring up the link only when traffic needs
+   to pass this link.  If the link fails for any reason, the link is brought
+   back up automatically once traffic passes the interface again. If you
+   configure an on-demand PPPoE connection, you must also configure the idle
+   timeout period, after which an idle PPPoE link will be disconnected. A
+   non-zero idle timeout will never disconnect the link after it first came up.
+
+.. cfgcmd:: set interfaces pppoe <interface> default-route
+
+   Use this command to specify whether to automatically add a default route
+   pointing to the endpoint of the PPPoE when the link comes up. The default
+   route is only added if no other default route already exists in the system.
+
+   **default:** A default route to the remote endpoint is automatically added
+   when the link comes up (i.e. auto).
+
+.. cfgcmd:: set interfaces pppoe <interface> idle-timeout <time>
+
+   Use this command to set the idle timeout interval to be used with on-demand
+   PPPoE sessions. When an on-demand connection is established, the link is
+   brought up only when traffic is sent and is disabled when the link is idle
+   for the interval specified.
+
+   If this parameter is not set or 0, an on-demand link will not be taken down
+   when it is idle and after the initial establishment of the connection. It
+   will stay up forever.
+
+.. cfgcmd:: set interfaces pppoe <interface> local-address <address>
+
+   Use this command to set the IP address of the local endpoint of a PPPoE
+   session. If it is not set it will be negotiated.
+
+.. cfgcmd:: set interfaces pppoe <interface> mtu <mtu>
+
+   Configure :abbr:`MTU (Maximum Transmission Unit)` on given `<interface>`. It
+   is the size (in bytes) of the largest ethernet frame sent on this link.
+
+.. cfgcmd:: set interfaces pppoe <interface> no-peer-dns
+
+   Use this command to not install advertised DNS nameservers into the local
+   system.
+
+.. cfgcmd:: set interfaces pppoe <interface> remote-address <address>
+
+   Use this command to set the IP address of the remote endpoint of a PPPoE
+   session. If it is not set it will be negotiated.
+
+.. cfgcmd:: set interfaces pppoe <interface> service-name <name>
+
+   Use this command to specify a service name by which the local PPPoE interface
+   can select access concentrators to connect with. It will connect to any
+   access concentrator if not set.
+
+.. cfgcmd:: set interfaces pppoe <interface> source-interface <source-interface>
+
+   Use this command to link the PPPoE connection to a physical interface. Each
+   PPPoE connection must be established over a physical interface. Interfaces
+   can be regular Ethernet interfaces, VIFs or bonding interfaces/VIFs.
+
+IPv6
+----
+
+.. cfgcmd:: set interfaces pppoe <interface> ipv6 enable
+
+   Use this command to enable IPv6 support on this PPPoE connection.
+
+.. cfgcmd:: set interfaces pppoe <interface> ipv6 address autoconf
+
+   Use this command to enable acquisition of IPv6 address using stateless
+   autoconfig (SLAAC).

+
+.. opcmd:: connect interface <interface>
+
+   Test connecting given connection-oriented interface. `<interface>` can be
+   ``pppoe0`` as example.
+
+*******
+Example
+*******
+
+Requirements:
+
+* Your ISPs modem is connected to port ``eth0`` of your VyOS box.
+* No VLAN tagging required by your ISP.
+* You need your PPPoE credentials from your DSL ISP in order to configure
+  this. The usual username is in the form of name@host.net but may vary
+  depending on ISP.
+* The largest MTU size you can use with DSL is 1492 due to PPPoE overhead.
+  If you are switching from a DHCP based ISP like cable then be aware that
+  things like VPN links may need to have their MTU sizes adjusted to work
+  within this limit.
+* With the ``default-route`` option set to ``auto``, VyOS will only add the
+  default gateway you receive from your DSL ISP to the routing table if you
+  have no other WAN connections. If you wish to use a dual WAN connection,
+  change the ``default-route`` option to ``force``.
+* With the ``name-server`` option set to ``none``, VyOS will ignore the
+  nameservers your ISP sens you and thus you can fully rely on the ones you
+  have configured statically.
+
+.. note:: Syntax has changed from VyOS 1.2 (crux) and it will be automatically
+   migrated during an upgrade.
+
+.. code-block:: none
+
+  set interfaces pppoe pppoe0 default-route 'auto'
+  set interfaces pppoe pppoe0 mtu 1492
+  set interfaces pppoe pppoe0 authentication user 'userid'
+  set interfaces pppoe pppoe0 authentication password 'secret'
+  set interfaces pppoe pppoe0 source-interface 'eth0'
+
+
+You should add a firewall to your configuration above as well by
+assigning it to the pppoe0 itself as shown here:
+
+.. code-block:: none
+
+  set interfaces pppoe pppoe0 firewall in name NET-IN
+  set interfaces pppoe pppoe0 firewall local name NET-LOCAL
+  set interfaces pppoe pppoe0 firewall out name NET-OUT
+
+VLAN Example
+============
+
+Some recent ISPs require you to build the PPPoE connection through a VLAN
+interface. One of those ISPs is e.g. Deutsche Telekom in Germany. VyOS
+can easily create a PPPoE session through an encapsulated VLAN interface.
+The following configuration will run your PPPoE connection through VLAN7
+which is the default VLAN for Deutsche Telekom:
+
+.. code-block:: none
+
+  set interfaces pppoe pppoe0 default-route 'auto'
+  set interfaces pppoe pppoe0 mtu 1492
+  set interfaces pppoe pppoe0 authentication user 'userid'
+  set interfaces pppoe pppoe0 authentication password 'secret'
+  set interfaces pppoe pppoe0 source-interface 'eth0.7'
+
+
+IPv6 DHCPv6-PD Example
+----------------------
+
+The following configuration will assign a /64 prefix out of a /56 delegation
+to eth0. The IPv6 address assigned to eth0 will be <prefix>::ffff/64.
+If you do not know the prefix size delegated to you, start with sla-len 0.
+
+.. code-block:: none
+
+  set interfaces pppoe pppoe0 authentication user vyos
+  set interfaces pppoe pppoe0 authentication password vyos
+  set interfaces pppoe pppoe0 dhcpv6-options prefix-delegation interface eth0 address 65535
+  set interfaces pppoe pppoe0 dhcpv6-options prefix-delegation interface eth0 sla-id 0
+  set interfaces pppoe pppoe0 dhcpv6-options prefix-delegation interface eth0 sla-len 8
+  set interfaces pppoe pppoe0 ipv6 address autoconf
+  set interfaces pppoe pppoe0 ipv6 enable
+  set interfaces pppoe pppoe0 source-interface eth1

+#######################
+Pseudo Ethernet/MACVLAN
+#######################
+
+Pseudo-Ethernet or MACVLAN interfaces can be seen as subinterfaces to regular
+ethernet interfaces. Each and every subinterface is created a different media
+access control (MAC) address, for a single physical Ethernet port. Pseudo-
+Ethernet interfaces have most of their application in virtualized environments,
+
+By using Pseudo-Ethernet interfaces there will be less system overhead compared
+to running a traditional bridging approach. Pseudo-Ethernet interfaces can also
+be used to workaround the general limit of 4096 virtual LANs (VLANs) per
+physical Ethernet port, since that limit is with respect to a single MAC
+address.
+
+Every Virtual Ethernet interfaces behaves like a real Ethernet interface. They
+can have IPv4/IPv6 addresses configured, or can request addresses by DHCP/
+DHCPv6 and are associated/mapped with a real ethernet port. This also makes
+Pseudo-Ethernet interfaces interesting for testing purposes. A Pseudo-Ethernet
+device will inherit characteristics (speed, duplex, ...) from its physical
+parent (the so called link) interface.
+
+Once created in the system, Pseudo-Ethernet interfaces can be referenced in
+the exact same way as other Ethernet interfaces. Notes about using Pseudo-
+Ethernet interfaces:
+
+* Pseudo-Ethernet interfaces can not be reached from your internal host. This
+  means that you can not try to ping a Pseudo-Ethernet interface from the host
+  system on which it is defined. The ping will be lost.
+* Loopbacks occurs at the IP level the same way as for other interfaces,
+  ethernet frames are not forwarded between Pseudo-Ethernet interfaces.
+* Pseudo-Ethernet interfaces may not work in environments which expect a
+  :abbr:`NIC (Network Interface Card)` to only have a single address. This
+  applies to:
+  - VMware machines using default settings
+  - Network switches with security settings allowing only a single MAC address
+  - xDSL modems that try to lear the MAC address of the NIC

+
+Tunnel
+======
+
+This article touches on 'classic' IP tunneling protocols.
+
+GRE is often seen as a one size fits all solution when it comes to classic IP
+tunneling protocols, and for a good reason. However, there are more specialized
+options, and many of them are supported by VyOS. There are also rather obscure
+GRE options that can be useful.
+
+All those protocols are grouped under ``interfaces tunnel`` in VyOS. Let's take
+a closer look at the protocols and options currently supported by VyOS.
+
+Common interface configuration
+------------------------------
+
+.. cmdinclude:: ../_include/interface-common-without-dhcp.txt
+   :var0: tunnel
+   :var1: tun0
+
+IPIP
+----
+
+This is one of the simplest types of tunnels, as defined by :rfc:`2003`.
+It takes an IPv4 packet and sends it as a payload of another IPv4 packet. For
+this reason, there are no other configuration options for this kind of tunnel.
+
+An example:
+
+.. code-block:: none
+
+  set interfaces tunnel tun0 encapsulation ipip
+  set interfaces tunnel tun0 local-ip 192.0.2.10
+  set interfaces tunnel tun0 remote-ip 203.0.113.20
+  set interfaces tunnel tun0 address 192.168.100.200/24
+
+IP6IP6
+------
+
+This is the IPv6 counterpart of IPIP. I'm not aware of an RFC that defines this
+encapsulation specifically, but it's a natural specific case of IPv6
+encapsulation mechanisms described in :rfc:2473`.
+
+It's not likely that anyone will need it any time soon, but it does exist.
+
+An example:
+
+.. code-block:: none
+
+  set interfaces tunnel tun0 encapsulation ip6ip6
+  set interfaces tunnel tun0 local-ip 2001:db8:aa::1
+  set interfaces tunnel tun0 remote-ip 2001:db8:aa::2
+  set interfaces tunnel tun0 address 2001:db8:bb::1/64
+
+IPIP6
+-----
+
+In the future this is expected to be a very useful protocol (though there are
+`other proposals`_).
+
+As the name implies, it's IPv4 encapsulated in IPv6, as simple as that.
+
+An example:
+
+.. code-block:: none
+
+  set interfaces tunnel tun0 encapsulation ipip6
+  set interfaces tunnel tun0 local-ip 2001:db8:aa::1

+
+6in4 (SIT)
+----------
+
+6in4 uses tunneling to encapsulate IPv6 traffic over IPv4 links as defined in
+:rfc:`4213`. The 6in4 traffic is sent over IPv4 inside IPv4 packets whose IP
+headers have the IP protocol number set to 41. This protocol number is
+specifically designated for IPv6 encapsulation, the IPv4 packet header is
+immediately followed by the IPv6 packet being carried. The encapsulation
+overhead is the size of the IPv4 header of 20 bytes, therefore with an MTU of
+1500 bytes, IPv6 packets of 1480 bytes can be sent without fragmentation. This
+tunneling technique is frequently used by IPv6 tunnel brokers like `Hurricane
+Electric`_.
+
+An example:
+
+.. code-block:: none
+
+  set interfaces tunnel tun0 encapsulation sit
+  set interfaces tunnel tun0 local-ip 192.0.2.10
+  set interfaces tunnel tun0 remote-ip 192.0.2.20
+  set interfaces tunnel tun0 address 2001:db8:bb::1/64
+

+
+Generic Routing Encapsulation (GRE)
+-----------------------------------
+
+A GRE tunnel operates at layer 3 of the OSI model and is repsented by IP
+protocol 47.The main benefit of a GRE tunnel is that you are able to route
+traffic across disparate networks. GRE also supports multicast traffic and
+supports routing protocols that leverage multicast to form neighbor adjacencies.
+
+Configuration
+^^^^^^^^^^^^^
+
+A basic configuration requires a tunnel source (local-ip), a tunnel destination
+(remote-ip), an encapsulation type (gre), and an address (ipv4/ipv6).Below is a
+configuration example taken from a VyOS router and a Cisco IOS router. The main
+difference between these two configurations is that VyOS requires you
+explicitly configure the encapsulation type. The Cisco router defaults to gre
+ip otherwise it would have to be configured as well.
+
+**VyOS Router:**
+
+.. code-block:: none
+
+  set interfaces tunnel tun100 address '10.0.0.1/30'
+  set interfaces tunnel tun100 encapsulation 'gre'
+  set interfaces tunnel tun100 local-ip '198.51.100.2'
+  set interfaces tunnel tun100 remote-ip '203.0.113.10'
+
+**Cisco IOS Router:**
+
+.. code-block:: none
+
+  interface Tunnel100
+  ip address 10.0.0.2 255.255.255.252
+  tunnel source 203.0.113.10
+  tunnel destination 198.51.100.2
+
+
+Tunnel keys
+^^^^^^^^^^^
+
+GRE is also the only classic protocol that allows creating multiple tunnels with the same source and destination due to its support for tunnel keys. Despite its name, this feature has nothing to do with security: it's simply an identifier that allows routers to tell one tunnel from another.
+
+An example:
+
+.. code-block:: none
+
+   set interfaces tunnel tun0 local-ip 192.0.2.10
+   set interfaces tunnel tun0 remote-ip 192.0.2.20
+   set interfaces tunnel tun0 address 10.40.50.60/24
+   set interfaces tunnel tun0 parameters ip key 10
+  
+.. code-block:: none
+
+   set interfaces tunnel tun0 local-ip 192.0.2.10
+   set interfaces tunnel tun0 remote-ip 192.0.2.20
+   set interfaces tunnel tun0 address 172.16.17.18/24
+   set interfaces tunnel tun0 parameters ip key 20
+
+
+Troubleshooting
+^^^^^^^^^^^^^^^
+
+GRE is a well defined standard that is common in most networks. While not
+inherently difficult to configure there are a couple of things to keep in mind
+to make sure the configuration performs as expected. A common cause for GRE
+tunnels to fail to come up correctly include ACL or Firewall configurations
+that are discarding IP protocol 47 or blocking your source/desintation traffic.
+
+**1. Confirm IP connectivity between tunnel local-ip and remote-ip:**
+
+.. code-block:: none
+
+  vyos@vyos:~$ ping 203.0.113.10 interface 198.51.100.2 count 4
+  PING 203.0.113.10 (203.0.113.10) from 198.51.100.2 : 56(84) bytes of data.

+**3. Confirm IP connectivity across the tunnel:**
+
+.. code-block:: none
+
+  vyos@vyos:~$ ping 10.0.0.2 interface 10.0.0.1 count 4
+  PING 10.0.0.2 (10.0.0.2) from 10.0.0.1 : 56(84) bytes of data.

+VXLAN
+#####
+
+:abbr:`VXLAN (Virtual Extensible LAN)` is a network virtualization technology
+that attempts to address the scalability problems associated with large cloud
+computing deployments. It uses a VLAN-like encapsulation technique to
+encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using
+4789 as the default IANA-assigned destination UDP port number. VXLAN
+endpoints, which terminate VXLAN tunnels and may be either virtual or physical
+switch ports, are known as :abbr:`VTEPs (VXLAN tunnel endpoints)`.
+
+VXLAN is an evolution of efforts to standardize on an overlay encapsulation
+protocol. It increases scalability up to 16 million logical networks and
+allows for layer 2 adjacency across IP networks. Multicast or unicast with
+head-end replication (HER) is used to flood broadcast, unknown unicast,
+and multicast (BUM) traffic.
+
+The VXLAN specification was originally created by VMware, Arista Networks
+and Cisco. Other backers of the VXLAN technology include Huawei, Broadcom,
+Citrix, Pica8, Big Switch Networks, Cumulus Networks, Dell EMC, Ericsson,
+Mellanox, FreeBSD, OpenBSD, Red Hat, Joyent, and Juniper Networks.
+
+VXLAN was officially documented by the IETF in :rfc:`7348`.
+
+If configuring VXLAN in a VyOS virtual machine, ensure that MAC spoofing
+(Hyper-V) or Forged Transmits (ESX) are permitted, otherwise forwarded frames
+may be blocked by the hypervisor.
+
+.. note:: As VyOS is based on Linux and there was no official IANA port assigned
+   for VXLAN, VyOS uses a default port of 8472. You can change the port on a
+   per VXLAN interface basis to get it working across multiple vendors.
+
+Configuration
+=============
+
+Common interface configuration
+------------------------------
+
+.. cmdinclude:: ../_include/interface-common-without-dhcp.txt
+  :var0: vxlan
+  :var1: vxlan0
+
+VXLAN specific options
+-----------------------
+
+.. cfgcmd:: set interfaces vxlan <interface> vni <number>
+
+  Each VXLAN segment is identified through a 24-bit segment ID, termed the
+  :abbr:`VNI (VXLAN Network Identifier (or VXLAN Segment ID))`, This allows
+  up to 16M VXLAN segments to coexist within the same administrative domain.
+
+.. cfgcmd:: set interfaces vxlan <interface> port <port>
+
+  Configure port number of remote VXLAN endpoint.
+
+  .. note:: As VyOS is Linux based the default port used is not using 4789
+     as the default IANA-assigned destination UDP port number. Instead VyOS
+     uses the Linux default port of 8472.
+
+.. cfgcmd:: set interfaces vxlan <interface> source-address <interface>
+
+  Source IP address used for VXLAN underlay. This is mandatory when using VXLAN
+  via L2VPN/EVPN.
+
+Unicast
+^^^^^^^
+
+.. cfgcmd:: set interfaces vxlan <interface> remote <address>
+
+  IPv4/IPv6 remote address of the VXLAN tunnel. Alternative to multicast, the
+  remote IPv4/IPv6 address can set directly.
+
+Multicast
+^^^^^^^^^
+
+.. cfgcmd:: set interfaces vxlan <interface> source-interface <interface>
+
+  Interface used for VXLAN underlay. This is mandatory when using VXLAN via
+  a multicast network. VXLAN traffic will always enter and exit this interface.
+
+
+.. cfgcmd:: set interfaces vxlan <interface> group <address>
+
+  Multicast group address for VXLAN interface. VXLAN tunnels can be built
+  either via Multicast or via Unicast.
+
+  Both IPv4 and IPv6 multicast is possible.
+
+Multicast VXLAN
+===============
+
+Topology: PC4 - Leaf2 - Spine1 - Leaf3 - PC5
+
+PC4 has IP 10.0.0.4/24 and PC5 has IP 10.0.0.5/24, so they believe they are in
+the same broadcast domain.
+
+Let's assume PC4 on Leaf2 wants to ping PC5 on Leaf3. Instead of setting Leaf3
+as our remote end manually, Leaf2 encapsulates the packet into a UDP-packet and
+sends it to its designated multicast-address via Spine1. When Spine1 receives
+this packet it forwards it to all other Leafs who has joined the same
+multicast-group, in this case Leaf3. When Leaf3 receives the packet it forwards
+it, while at the same time learning that PC4 is reachable behind Leaf2, because
+the encapsulated packet had Leaf2's IP-address set as source IP.
+
+PC5 receives the ping echo, responds with an echo reply that Leaf3 receives and
+this time forwards to Leaf2's unicast address directly because it learned the
+location of PC4 above. When Leaf2 receives the echo reply from PC5 it sees that
+it came from Leaf3 and so remembers that PC5 is reachable via Leaf3.
+
+Thanks to this discovery, any subsequent traffic between PC4 and PC5 will not
+be using the multicast-address between the Leafs as they both know behind which
+Leaf the PCs are connected. This saves traffic as less multicast packets sent
+reduces the load on the network, which improves scalability when more Leafs are
+added.
+
+For optimal scalability Multicast shouldn't be used at all, but instead use BGP
+to signal all connected devices between leafs. Unfortunately, VyOS does not yet
+support this.
+
+Example
+-------
+
+The setup is this: Leaf2 - Spine1 - Leaf3
+
+Spine1 is a Cisco IOS router running version 15.4, Leaf2 and Leaf3 is each a
+VyOS router running 1.2.
+
+This topology was built using GNS3.
+
+Topology:
+
+.. code-block:: none
+
+  Spine1:
+  fa0/2 towards Leaf2, IP-address: 10.1.2.1/24
+  fa0/3 towards Leaf3, IP-address: 10.1.3.1/24
+
+  Leaf2:
+  Eth0 towards Spine1, IP-address: 10.1.2.2/24
+  Eth1 towards a vlan-aware switch
+
+  Leaf3:
+  Eth0 towards Spine1, IP-address 10.1.3.3/24
+  Eth1 towards a vlan-aware switch
+
+**Spine1 Configuration:**
+
+.. code-block:: none
+
+  conf t
+  ip multicast-routing
+  !
+  interface fastethernet0/2
+   ip address 10.1.2.1 255.255.255.0
+   ip pim sparse-dense-mode
+  !
+  interface fastethernet0/3
+   ip address 10.1.3.1 255.255.255.0
+   ip pim sparse-dense-mode
+  !
+  router ospf 1
+   network 10.0.0.0 0.255.255.255 area 0
+
+Multicast-routing is required for the leafs to forward traffic between each
+other in a more scalable way. This also requires PIM to be enabled towards the
+Leafs so that the Spine can learn what multicast groups each Leaf expect
+traffic from.
+
+**Leaf2 configuration:**
+
+.. code-block:: none
+
+  set interfaces ethernet eth0 address '10.1.2.2/24'
+  set protocols ospf area 0 network '10.0.0.0/8'
+
+  ! Our first vxlan interface
+  set interfaces bridge br241 address '172.16.241.1/24'
+  set interfaces bridge br241 member interface 'eth1.241'
+  set interfaces bridge br241 member interface 'vxlan241'
+
+  set interfaces vxlan vxlan241 group '239.0.0.241'
+  set interfaces vxlan vxlan241 source-interface 'eth0'
+  set interfaces vxlan vxlan241 vni '241'
+
+  ! Our seconds vxlan interface
+  set interfaces bridge br242 address '172.16.242.1/24'
+  set interfaces bridge br242 member interface 'eth1.242'
+  set interfaces bridge br242 member interface 'vxlan242'
+
+  set interfaces vxlan vxlan242 group '239.0.0.242'
+  set interfaces vxlan vxlan242 source-interface 'eth0'
+  set interfaces vxlan vxlan242 vni '242'
+
+**Leaf3 configuration:**
+
+.. code-block:: none
+
+  set interfaces ethernet eth0 address '10.1.3.3/24'
+  set protocols ospf area 0 network '10.0.0.0/8'
+
+  ! Our first vxlan interface
+  set interfaces bridge br241 address '172.16.241.1/24'
+  set interfaces bridge br241 member interface 'eth1.241'
+  set interfaces bridge br241 member interface 'vxlan241'
+
+  set interfaces vxlan vxlan241 group '239.0.0.241'
+  set interfaces vxlan vxlan241 source-interface 'eth0'
+  set interfaces vxlan vxlan241 vni '241'
+
+  ! Our seconds vxlan interface
+  set interfaces bridge br242 address '172.16.242.1/24'
+  set interfaces bridge br242 member interface 'eth1.242'
+  set interfaces bridge br242 member interface 'vxlan242'
+
+  set interfaces vxlan vxlan242 group '239.0.0.242'
+  set interfaces vxlan vxlan242 source-interface 'eth0'
+  set interfaces vxlan vxlan242 vni '242'
+
+As you can see, Leaf2 and Leaf3 configuration is almost identical. There are
+lots of commands above, I'll try to into more detail below, command
+descriptions are placed under the command boxes:
+
+.. code-block:: none
+
+  set interfaces bridge br241 address '172.16.241.1/24'
+
+This commands creates a bridge that is used to bind traffic on eth1 vlan 241
+with the vxlan241-interface. The IP-address is not required. It may however be
+used as a default gateway for each Leaf which allows devices on the vlan to
+reach other subnets. This requires that the subnets are redistributed by OSPF
+so that the Spine will learn how to reach it. To do this you need to change the
+OSPF network from '10.0.0.0/8' to '0.0.0.0/0' to allow 172.16/12-networks to be
+advertised.
+
+.. code-block:: none
+
+  set interfaces bridge br241 member interface 'eth1.241'
+  set interfaces bridge br241 member interface 'vxlan241'
+
+Binds eth1.241 and vxlan241 to each other by making them both member interfaces of
+the same bridge.
+
+.. code-block:: none
+
+  set interfaces vxlan vxlan241 group '239.0.0.241'
+
+The multicast-group used by all Leafs for this vlan extension. Has to be the
+same on all Leafs that has this interface.
+
+.. code-block:: none
+
+  set interfaces vxlan vxlan241 source-interface 'eth0'
+
+Sets the interface to listen for multicast packets on. Could be a loopback, not
+yet tested.
+
+.. code-block:: none
+
+  set interfaces vxlan vxlan241 vni '241'
+
+Sets the unique id for this vxlan-interface. Not sure how it correlates with
+multicast-address.
+
+.. code-block:: none
+
+  set interfaces vxlan vxlan241 port 12345
+
+The destination port used for creating a VXLAN interface in Linux defaults to
+its pre-standard value of 8472 to preserve backwards compatibility. A
+configuration directive to support a user-specified destination port to override
+that behavior is available using the above command.
+
+Unicast VXLAN
+=============
+
+Alternative to multicast, the remote IPv4 address of the VXLAN tunnel can be
+set directly. Let's change the Multicast example from above:
+
+.. code-block:: none
+
+  # leaf2 and leaf3
+  delete interfaces vxlan vxlan241 group '239.0.0.241'
+  delete interfaces vxlan vxlan241 source-interface 'eth0'
+
+  # leaf2
+  set interface vxlan vxlan241 remote 10.1.3.3
+
+  # leaf3
+  set interface vxlan vxlan241 remote 10.1.2.2
+
+The default port udp is set to 8472.
+It can be changed with ``set interface vxlan <vxlanN> port <port>``

+WireGuard
+#########
+
+WireGuard is an extremely simple yet fast and modern VPN that utilizes
+state-of-the-art cryptography. See https://www.wireguard.com for more
+information.
+
+Configuration
+=============
+
+WireGuard requires the generation of a keypair, a private key which will
+decrypt incoming traffic and a public key, which the peer(s) will use to
+encrypt traffic.
+
+Generate keypair
+----------------
+
+.. opcmd:: generate wireguard default-keypair
+
+   It generates the keypair, that is its public and private part and stores
+   it within VyOS. It will be used per default on any configured WireGuard
+   interface, even if multiple interfaces are being configured.
+
+.. opcmd:: show wireguard keypairs pubkey default
+
+   It shows the public key which needs to be shared with your peer(s). Your
+   peer will encrypt all traffic to your system using this public key.
+
+   .. code-block:: none
+
+     vyos@vyos:~$ show wireguard keypairs pubkey default
+     hW17UxY7zeydJNPIyo3UtGnBHkzTK/NeBOrDSIU9Tx0=
+
+
+Generate named keypair
+----------------------
+
+Named keypairs can be used on a interface basis, if configured. If
+multiple WireGuard interfaces are being configured, each can have their
+own keypairs.
+
+The commands below will generate 2 keypairs, which are not related to
+each other.
+
+.. code-block:: none
+
+  vyos@vyos:~$ generate wireguard named-keypairs KP01
+  vyos@vyos:~$ generate wireguard named-keypairs KP02
+
+
+Interface configuration
+-----------------------
+
+The next step is to configure your local side as well as the policy
+based trusted destination addresses. If you only initiate a connection,
+the listen port and address/port is optional, if you however act as a server
+and endpoints initiate the connections to your system, you need to
+define a port your clients can connect to, otherwise it's randomly
+chosen and may make it difficult with firewall rules, since the port may
+be a different one when you reboot your system.
+
+You will also need the public key of your peer as well as the network(s)
+you want to tunnel (allowed-ips) to configure a WireGuard tunnel. The
+public key below is always the public key from your peer, not your local
+one.
+
+**local side**
+
+.. code-block:: none
+
+  set interfaces wireguard wg01 address '10.1.0.1/24'
+  set interfaces wireguard wg01 description 'VPN-to-wg02'
+  set interfaces wireguard wg01 peer to-wg02 allowed-ips '10.2.0.0/24'
+  set interfaces wireguard wg01 peer to-wg02 address '192.168.0.142'
+  set interfaces wireguard wg01 peer to-wg02 port '12345'
+  set interfaces wireguard wg01 peer to-wg02 pubkey 'XMrlPykaxhdAAiSjhtPlvi30NVkvLQliQuKP7AI7CyI='
+  set interfaces wireguard wg01 port '12345'
+  set protocols static interface-route 10.2.0.0/24 next-hop-interface wg01
+
+The last step is to define an interface route for 10.2.0.0/24 to get
+through the WireGuard interface `wg01`. Multiple IPs or networks can be
+defined and routed, the last check is allowed-ips which either prevents
+or allows the traffic.
+
+.. note:: You can not assign the same allowed-ips statement to multiple
+   WireGuard peers. This a a design decission. For more information please
+   check the `WireGuard mailing list`_.
+
+
+To use a named key on an interface, the option private-key needs to be
+set.
+
+.. code-block:: none
+
+  set interfaces wireguard wg01 private-key KP01
+  set interfaces wireguard wg02 private-key KP02
+
+The command ``run show wireguard keypairs pubkey KP01`` will then show
+the public key, which needs to be shared with the peer.
+
+
+**remote side**
+
+.. code-block:: none
+
+  set interfaces wireguard wg01 address '10.2.0.1/24'
+  set interfaces wireguard wg01 description 'VPN-to-wg01'
+  set interfaces wireguard wg01 peer to-wg02 allowed-ips '10.1.0.0/24'
+  set interfaces wireguard wg01 peer to-wg02 address '192.168.0.124'
+  set interfaces wireguard wg01 peer to-wg02 port '12345'
+  set interfaces wireguard wg01 peer to-wg02 pubkey 'u41jO3OF73Gq1WARMMFG7tOfk7+r8o8AzPxJ1FZRhzk='
+  set interfaces wireguard wg01 port '12345'
+  set protocols static interface-route 10.1.0.0/24 next-hop-interface wg01
+
+Assure that your firewall rules allow the traffic, in which case you
+have a working VPN using WireGuard
+

+Road Warrior Example
+--------------------
+
+With WireGuard, a Road Warrior VPN config is similar to a site-to-site
+VPN. It just lacks the ``address`` and ``port`` statements.
+
+In the following example, the IPs for the remote clients are defined in
+the peers. This would allow the peers to interact with one another.
+
+.. code-block:: none
+
+    wireguard wg0 {
+        address 10.172.24.1/24

+Wireless LAN (WiFi)
+###################
+
+:abbr:`WLAN (Wireless LAN)` interface provide 802.11 (a/b/g/n/ac) wireless
+support (commonly referred to as Wi-Fi) by means of compatible hardware. If your
+hardware supports it, VyOS supports multiple logical wireless interfaces per
+physical device.
+
+There are three modes of operation for a wireless interface:
+
+* :abbr:`WAP (Wireless Access-Point)` provides network access to connecting
+  stations if the physical hardware supports acting as a WAP
+
+* A station acts as a Wi-Fi client accessing the network through an available
+  WAP
+
+* Monitor, the system passively monitors any kind of wireless traffic
+
+If the system detects an unconfigured wireless device, it will be automatically
+added the configuration tree, specifying any detected settings (for example,
+its MAC address) and configured to run in monitor mode.

+Wireless options (Station/Client)
+=================================
+
+The example creates a wireless station (commonly referred to as Wi-Fi client)
+that accesses the network through the WAP defined in the above example. The

+
+Security
+========
+
+:abbr:`WPA (Wi-Fi Protected Access)` and WPA2 Enterprise in combination with
+802.1x based authentication can be used to authenticate users or computers
+in a domain.
+
+The wireless client (supplicant) authenticates against the RADIUS server
+(authentication server) using an :abbr:`EAP (Extensible Authentication
+Protocol)`  method configured on the RADIUS server. The WAP (also referred
+to as authenticator) role is to send all authentication messages between the
+supplicant and the configured authentication server, thus the RADIUS server
+is responsible for authenticating the users.
+
+The WAP in this example has the following characteristics:
+
+* IP address ``192.168.2.1/24``
+* Network ID (SSID) ``Enterprise-TEST``
+* WPA passphrase ``12345678``
+* Use 802.11n protocol

+Examples
+********
+
+The following example creates a WAP. When configuring multiple WAP interfaces,
+you must specify unique IP addresses, channels, Network IDs commonly referred
+to as :abbr:`SSID (Service Set Identifier)`, and MAC addresses.
+
+The WAP in this example has the following characteristics:
+
+* IP address ``192.168.2.1/24``
+* Network ID (SSID) ``TEST``
+* WPA passphrase ``12345678``
+* Use 802.11n protocol
+* Wireless channel ``1``
+
+.. code-block:: none
+
+  set interfaces wireless wlan0 address '192.168.2.1/24'
+  set interfaces wireless wlan0 type access-point
+  set interfaces wireless wlan0 channel 1
+  set interfaces wireless wlan0 mode n
+  set interfaces wireless wlan0 ssid 'TEST'
+  set interfaces wireless wlan0 security wpa mode wpa2
+  set interfaces wireless wlan0 security wpa cipher CCMP
+  set interfaces wireless wlan0 security wpa passphrase '12345678'
+
+Resulting in
+
+.. code-block:: none
+
+  interfaces {
+    [...]
+    wireless wlan0 {
+          address 192.168.2.1/24
+          channel 1
+          mode n
+          security {
+              wpa {
+                  cipher CCMP
+                  mode wpa2
+                  passphrase "12345678"
+              }
+          }
+          ssid "TEST"
+          type access-point
+      }
+  }
+  system {
+    [...]
+    wifi-regulatory-domain DE
+  }
+
+To get it to work as a access point with this configuration you will need
+to set up a DHCP server to work with that network. You can - of course - also
+bridge the Wireless interface with any configured bridge
+(:ref:`bridge-interface`) on the system.

+WirelessModem (WWAN)
+####################
+
+The wirelessmodem interface provides access (through a wireless modem/wwan)
+to wireless networks provided by various cellular providers. VyOS uses the
+interfaces wirelessmodem subsystem for configuration.
+
+*************
+Configuration
+*************
+
+Common interface configuration
+==============================
+
+.. cmdinclude:: ../_include/interface-description.txt
+   :var0: wirelessmodem
+   :var1: wlm0
+
+.. cmdinclude:: ../_include/interface-disable.txt
+   :var0: wirelessmodem
+   :var1: wlm0
+
+.. cmdinclude:: ../_include/interface-vrf.txt
+   :var0: wirelessmodem
+   :var1: wlm0
+
+WirelessModem (WWAN) options
+============================
+
+.. cfgcmd:: set interfaces wirelessmodem <interface> apn <apn>
+
+   Every WWAN connection requires an :abbr:`APN (Access Point Name)` which is
+   used by the client to dial into the ISPs network. This is a mandatory
+   parameter. Contact your Service Provider for correct APN.
+
+.. cfgcmd:: set interfaces wirelessmodem <interface> backup distance <metric>
+
+   Configure metric of the default route added via the Wireless Modem interface.
+   The default metric if not specified is 10.
+
+.. cfgcmd:: set interfaces wirelessmodem <interface> device <tty>
+
+   Device identifier of the underlaying physical interface. This is usually a
+   ttyUSB device, if not configured this defaults to ttyUSB2.
+
+.. cfgcmd:: set interfaces wirelessmodem <interface> no-peer-dns
+
+   Do not install DNS nameservers received from ISP into system wide nameserver
+   list.
+
+.. cfgcmd:: set interfaces wirelessmodem <interface> connect-on-demand
+
+   When set the interface is enabled for "dial-on-demand".
+
+   Use this command to instruct the system to establish a PPP connection
+   automatically once traffic passes through the interface. A disabled on-demand
+   connection is established at boot time and remains up. If the link fails for
+   any reason, the link is brought back up immediately.
+
