IPoE Server
###########
VyOS utilizes `accel-ppp`_ to provide :abbr:`IPoE (Internet Protocol over
Ethernet)` server functionality. It can be used with local authentication
(mac-address) or a connected RADIUS server.
IPoE is a method of delivering an IP payload over an Ethernet-based access
network or an access network using bridged Ethernet over Asynchronous Transfer
Mode (ATM) without using PPPoE. It directly encapsulates the IP datagrams in
Ethernet frames, using the standard :rfc:`894` encapsulation.
The use of IPoE addresses the disadvantage that PPP is unsuited for multicast
delivery to multiple users. Typically, IPoE uses Dynamic Host Configuration
Protocol and Extensible Authentication Protocol to provide the same
functionality as PPPoE, but in a less robust manner.
.. note:: Please be aware, due to an upstream bug, config changes/commits
will restart the ppp daemon and will reset existing IPoE sessions,
in order to become effective.
Configuration
=============
IPoE can be configure on different interfaces, it will depend on each specific
situation which interface will provide IPoE to clients. The clients mac address
and the incoming interface is being used as control parameter, to authenticate
a client.
The example configuration below will assign an IP to the client on the incoming
interface eth2 with the client mac address 08:00:27:2f:d8:06. Other DHCP
discovery requests will be ignored, unless the client mac has been enabled in
the configuration.
.. code-block:: none
set service ipoe-server authentication interface eth2 mac-address 08:00:27:2f:d8:06
set service ipoe-server authentication mode 'local'
set service ipoe-server dns-server server-1 '8.8.8.8'
set service ipoe-server dns-server server-2 '8.8.4.4'
set service ipoe-server interface eth2 client-subnet '192.168.0.0/24'
The first address of the parameter ``client-subnet``, will be used as the
default gateway. Connected sessions can be checked via the ``show ipoe-server
sessions`` command.
.. code-block:: none
vyos@vyos:~$ show ipoe-server sessions
ifname | called-sid | calling-sid | ip | ip6 | ip6-dp | rate-limit | state | uptime | sid
-------+------------+-------------------+-------------+-----+--------+------------+--------+----------+------------------
ipoe0 | eth2 | 08:00:27:2f:d8:06 | 192.168.0.2 | | | | active | 00:45:05 | dccc870fd3134612
IPv6 SLAAC and IA-PD
--------------------
To configure IPv6 assignments for clients, two options need to be configured.
A global prefix which is terminated on the clients cpe and a delegated prefix,
the client can use for devices routed via the clients cpe.
IPv6 DNS addresses are optional.
.. code-block:: none
set service ipoe-server authentication interface eth3 mac-address 08:00:27:2F:D8:06
set service ipoe-server authentication mode 'local'
set service ipoe-server client-ipv6-pool delegate-prefix '2001:db8:1::/48,56'
set service ipoe-server client-ipv6-pool prefix '2001:db8::/48,64'
set service ipoe-server dnsv6-server server-1 '2001:db8::'
set service ipoe-server dnsv6-server server-2 '2001:db8:aaa::'
set service ipoe-server dnsv6-server server-3 '2001:db8:bbb::'
set service ipoe-server interface eth3 client-subnet '192.168.1.0/24'
.. code-block:: none
vyos@ipoe-server# run sh ipoe-server sessions
ifname | called-sid | calling-sid | ip | ip6 | ip6-dp | rate-limit | state | uptime | sid
-------+------------+-------------------+-------------+---------------------------------+-----------------+------------+--------+----------+------------------
ipoe0 | eth3 | 08:00:27:2f:d8:06 | 192.168.1.2 | 2001:db8::a00:27ff:fe2f:d806/64 | 2001:db8:1::/56 | | active | 01:02:59 | 4626faf71b12cc25
The clients :abbr:`CPE (Customer Premises Equipment)` can now communicate via
IPv4 or IPv6. All devices behind ``2001:db8::a00:27ff:fe2f:d806/64`` can use
addresses from ``2001:db8:1::/56`` and can globally communicate without the
need of any NAT rules.
Automatic VLAN creation
-----------------------
To create VLANs per user during runtime, the following settings are required on
a per interface basis. VLAN ID and VLAN range can be present in the
configuration at the same time.
.. code-block:: none
set service ipoe-server interface eth2 network vlan
set service ipoe-server interface eth2 vlan-id 100
set service ipoe-server interface eth2 vlan-id 200
set service ipoe-server interface eth2 vlan-range 1000-2000
set service ipoe-server interface eth2 vlan-range 2500-2700
RADIUS Setup
------------
To use a RADIUS server for authentication and bandwidth-shaping, the following
example configuration can be used.
.. code-block:: none
set service ipoe-server authentication mode 'radius'
set service ipoe-server authentication radius-server 10.100.100.1 secret 'password'
Bandwidth Shaping
=================
Bandwidth rate limits can be set for local users within the configuration or
via RADIUS based attributes.
Bandwidth Shaping for local users
---------------------------------
The rate-limit is set in kbit/sec.
.. code-block:: none
set service ipoe-server authentication interface eth2 mac-address 08:00:27:2f:d8:06 rate-limit download '500'
set service ipoe-server authentication interface eth2 mac-address 08:00:27:2f:d8:06 rate-limit upload '500'
set service ipoe-server authentication mode 'local'
set service ipoe-server dns-server server-1 '8.8.8.8'
set service ipoe-server dns-server server-2 '8.8.4.4'
set service ipoe-server interface eth2 client-subnet '192.168.0.0/24'
.. code-block:: none
vyos@vyos# run show ipoe-server sessions
ifname | called-sid | calling-sid | ip | ip6 | ip6-dp | rate-limit | state | uptime | sid
-------+------------+-------------------+-------------+-----+--------+------------+--------+----------+------------------
ipoe0 | eth2 | 08:00:27:2f:d8:06 | 192.168.0.2 | | | 500/500 | active | 00:00:05 | dccc870fd31349fb
