When removing bgp (vrf) instances the assigned VRF vni must be deleted from FRR
prior the removal of the bgp settings (T3734).
This is now done by moving the CLI command "set vrf name red vni 1000" to a
dedicated Python script with a priority higher then bgp.

Commit 472c9568 ("isis: T3693: Adding IPv6 redistribution to ISIS") did not
pass rendering, am exception got thrown:
jinja2.exceptions.UndefinedError: 'dict object' has no attribute 'protocol'
This commit fixes the templateing code.

isis: T3693: Adding IPv6 redistribution to ISIS
|
|
In this commit we add the ability to redistribute into
ISIS for IPv6 address family.

Thi adds a new configuration level "set extcommunity" which then holds rt and
soo als leaf-nodes below. This is the foundational work required to
properly implement T3624 ("BGP: add support for extended community bandwidth
definition")

The BGP confederation peers node was not a multi node as supported by VyOS 1.2
and 1.3.

Commit 4f9aa30f ("vrf: bgp: T3523: add route-map support for kernel routes")
added the possibility to also filter BGP routes towards the OS kernel, but the
smoketests failed. Reason was a non working CLI command applied to bgpd.
Thus the VRF route-map and the BGP configuration is now split into two templates,
one to be used for each daemon (zebra and bgpd).
Nevertheless one more bug was found in vyos.frr which currently does not suppoort
calling modify_section() inside a configuration "block". See [1] for more info.

A + simply adds the value, but a ~ will convert the variable to a string
first.
|
|
This commit has a dependecy on https://github.com/FRRouting/frr/issues/8403,
thus support will be "commented out" by default.

This reverts commit 619c518bfc904b060b5b59180940a804fe1beafd.

When rendering a dynamic routing protocol ensure the context, e.g. "router bgp"
or "router ospf" is proberly exited before applying any zebra route-map.
|
|
|
|
The following options one can specify in a route-map not got rendered as they
have been missed out:
* set comm-list
* set community
* set extcommunity (both route-target and site-of-origin)
* set table

In this commit we add more address families within
BGP. This should bring VyOS the ability to enable
the rest of the capabilities within FRR.

Removing the Zebra/Linux Kernel route-map added by "set protocols rip route-map"
was not removed once applied. This was because the removal must happen within
the zebra daemon and not ripd.

Removing the Zebra/Linux Kernel route-map added by "set protocols isis route-map"
was not removed once applied. This was because the removal must happen within
the zebra daemon and not isisd.

set vrf name red protocols bgp address-family l2vpn-evpn advertise ipv4 unicast
|
|
This is a fix for commit 6f6f45c5 ("bgp: T3463: change no-ipv4-unicast order
when applying configuration") as this changed the handling of the "else" path,
which lead to failing smoketests as the "no bgp ebgp-requires-policy" option
was no longer set.
|
|
The "no bgp default ipv4-unicast" option must be applied to FRR before adding
any neighbor to the system. If this is not the case, neighbors will start
exchanging v4 routes over v6 peers.
|
|
Commit 548d9057e3e (vrf: T3344: move dynamic routing protocols under "vrf name
<name> protocols") temporary removed the possibility to specify the VNI for a
given VRF to to changing of the CLI configuration nodes.
As VNI is set inside zebra, we can re-use the now widely deployed frr python
library to configure and change the configuration without any interference to
other FRR daemons.

Every time when set configuration bgp, you need set AS number. There is very
less benefit in this system so the AS number is moved from a tagNode level down
to a leafNode with the name "local-as", same as on the neighbor or peer-group
level.
This changes the CLI configuration from:
set protocols bgp 100 neighbor 10.10.1.2 remote-as 200
to
set protocols bgp local-as 100
set protocols bgp neighbor 10.10.1.2 remote-as 200
|
|
As we and FRR do not support multiple FRR process instances, there is no need
to make this configurable for a user. We rather rely on a solid default "VyOS".
|
|
VRF support can be tested using:
set vrf name red table 1000
set vrf name red protocols isis domain FOOO
set vrf name red protocols isis net 49.0001.1921.6800.1002.00
set vrf name red protocols isis interface eth1
|
|
As there can only be one running IS-IS process (FRR limitation) there is no need
in having a tagNode here. This adds artifical restrictions/limitations when
moving on to support VRFs for IS-IS protocol.
|
|
Instead of having the dynamic routing protocols OSPF and BGP residing under
the "protocols vrf <name> [ospf|bgp]" nodes, rather move them directly under
the "vrf name <name> protocols [ospf|bgp]" node. Now all VRF related parts
are placed under the same root node.
This eases the verify steps tremendously, as we do not need to check wheter a
VRF eists or not, it will always exist as we operate under a child node.

The following VyOS CLI config
vrf red {
bgp 100 {
neighbor 1.1.1.1 {
peer-group foo
}
peer-group foo {
passive
password bar
remote-as 200
}
}
}
Will generaste the FRR configuration:
!
router bgp 100 vrf red
no bgp ebgp-requires-policy
no bgp network import-check
neighbor foo peer-group
neighbor foo remote-as 200
neighbor foo password bar
neighbor foo passive
neighbor 1.1.1.1 peer-group foo
!
