vxlan: T5668: add CLI knob to enable ARP/ND suppression
2023-10-30vxlan: T5699: migrate "external" CLI know to "parameters external"Christian Breunig
As we have a bunch of options under "paramteres" already and "external" is clearly one of them it should be migrated under that node as well.
2023-10-30vxlan: T5668: add CLI knob to enable ARP/ND suppressionChristian Breunig
In order to minimize the flooding of ARP and ND messages in the VXLAN network, EVPN includes provisions [1] that allow participating VTEPs to suppress such messages in case they know the MAC-IP binding and can reply on behalf of the remote host. In Linux, the above is implemented in the bridge driver using a per-port option called "neigh_suppress" that was added in kernel version 4.15. [1] https://www.rfc-editor.org/rfc/rfc7432#section-10

2023-09-09vxlan: T3700: support VLAN tunnel mapping of VLAN aware bridgesChristian Breunig
FRR supports a new way of configuring VLAN-to-VNI mappings for EVPN-VXLAN, when working with the Linux kernel. In this new way, the mapping of a VLAN to a VNI is configured against a container VXLAN interface which is referred to as a 'Single VXLAN device (SVD)'. Multiple VLAN to VNI mappings can be configured against the same SVD. This allows for a significant scaling of the number of VNIs since a separate VXLAN interface is no longer required for each VNI. Sample configuration of SVD with VLAN to VNI mappings is shown below. set interfaces bridge br0 member interface vxlan0 set interfaces vxlan vxlan0 external set interfaces vxlan vxlan0 source-interface 'dum0' set interfaces vxlan vxlan0 vlan-to-vni 10 vni '10010' set interfaces vxlan vxlan0 vlan-to-vni 11 vni '10011' set interfaces vxlan vxlan0 vlan-to-vni 30 vni '10030' set interfaces vxlan vxlan0 vlan-to-vni 31 vni '10031'

2022-12-30T4897: Fix virtual interface rebuild checksYuxiang Zhu
`leaf_node_changed` returns `[]` (empty list) after a leaf node is added. e.g. Setting `source-interface` doesn't work on an existing vxlan interface. Steps to reproduce: - Add a vxlan interface without `source-address` or `source-interface` options set: ``` set interfaces vxlan vxlan999 vni 999 set interfaces vxlan vxlan999 remote 192.168.100.100 commit ``` - Then set `source-address` or `source-interface`: ``` set interfaces vxlan vxlan999 source-interface eth0 commit ``` Actual result: Source address or source-interface are not set: ``` ip -d link show dev vxlan999 76: vxlan999: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/ether 56:08:ba:4d:4e:a8 brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 vxlan id 999 remote 192.168.100.100 srcport 0 0 dstport 8472 tos inherit ttl 16 ageing 300 udpcsum noudp6zerocsumtx noudp6zerocsumrx addrgenmode none numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 ``` Expected result: ``` 77: vxlan999: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/ether 9e:05:d9:58:1a:af brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 vxlan id 999 remote 192.168.100.100 dev eth0 srcport 0 0 dstport 8472 tos inherit ttl 16 ageing 300 udpcsum noudp6zerocsumtx noudp6zerocsumrx addrgenmode none numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 ``` All invocations of leaf_node_changed() should be migrated to is_node_changes() if you are only interested in if something changed and don‘t care what exactly changed (content).
2022-07-28vxlan: T4570: Verify MTU for remote address if source not definedViacheslav Hletenko
In some cases `source_address` can be not defined in the conf So we should to check list of `remote` vxlanX addresses If remote address is IPv6 - add overhead +20 bytes to default overhead 50. I.e. +70 bytes for IPv6

2022-04-25vyos.configdict: T4391: enable get_interface_dict() ti be used with ↵Christian Poessinger
ConfigTreeQuery() When VyOS is booting and an interface is brought up (PPPoE) which requires a user callback script that is executed asynchronously when the interface is up we can not use Config(). The problem is, Config() is not available when the system starts and the initial commit is still processed. We need to move to ConfigTreeQuery() which was build for this exact same purpose. TO reduce side effects and also dependencies on the entire vyos.configdict library the set_level()/get_level() calls got eliminated from within the library. All calls to functions like: * get_removed_vlans() * is_node_changed() * leaf_node_changed() * is_mirror_intf() * ... Now require that the full config path to the node is passed.

When changing "general" parameters like: - interface IP address - MTU - description the interface is destroyed and recreated ... this should not happen!

VXLAN does support using multiple remotes but VyOS does not. Add the ability to set multiple remotes and add their flood lists using "bridge" command.

2021-07-17vxlan: T3683: bugfix on MTU calculation for IPv6 underlayChristian Poessinger
2021-02-28vyos.ifconfig: T1579: remove calls to vyos.ifconfig.Interface.get_config()Christian Poessinger
Interface.get_config() was always a pure helper which exposed a "per interface type" dictionary which was then fed by the caller to create interfaces by iproute2 which required additional options during creation time. Such interfaces had been: * tunnel * vxlan * geneve * macsec * wifi * macvlan / pseudo-ethernet The code was always duplicated to convert from the VyOS CLI based get_config_dict() to a dict which can be used to feed iproute2. This path has been removed and we now always feed in the entire dictionary retrieved by get_config_dict() or in the interfaces case, it's high-level wrapper get_interface_dict() to the interface we wan't to create. This also adds the - personally long awaited - possibility to get rid of the derived tunnel classes for e.g. GRE, IPIP, IPIP6 and so on.

Introduced in commit 818a75c024e ("ifconfig: T2653: get_mtu() should return int() for easier comparison") where the variable used in the formatted string has not been adjusted.
2020-09-26ifconfig: mtu: disallow MTU < 1280 bytes when IPv6 is enabled on the interfaceChristian Poessinger
Using an MTU less then the required 1280 bytes (as per RFC) on an interface where IPv6 is not explicitly disabled by: - set interfaces ethernet eth1 ipv6 address no-default-link-local - not having any other IPv6 address configured Will now trigger a commit error via verify() instead of raising FileNotFoundError!

2020-09-20ifconfig: T2653: remove duplicates of get_config()Christian Poessinger
A lot of derived classes from Interface implemented their own get_config() method which more or less was the same everywhere. We also hat different qualifiers like @staticmethod or @classmethod. This is now changed to only have the @classmethod in Interface base class which will return the necessary dictionary keys for the required interfaces. This change is a mid reduction in lines of code which is always a very nice thing!

2020-07-26vxlan: ifconfig: T2653: move to get_interface_dict()Christian Poessinger
The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge.

This is a base requirement for l2vpn evpn. When source-address is configured, the option "local <source-addr> nolearning" is appended when creating the interface as mentioned here: https://vincent.bernat.ch/en/blog/2017-vxlan-bgp-evpn
