You’ll see my tester opening the BGP session first and giving in the capabilities IPv6 Unicast. The OPEN in response from Quagga is missing the IPv6/Unicast AFI/SAFI

Weird. You have it configured. So the 'activate' statement led to peer_activate being called and:

   peer->afc[afi][safi] = 1;

surely was called. And bgp_open_capability uses that to write out the capability advertisement.

So how was it not in the OPEN?

Here is the relevant config from the Quagga Side:

Current configuration:
! ! [...] ! interface eth2
 ip address 192.168.1.101/24
 ipv6 address fc00:192:168:1::101/64
! ! [...] ! router bgp 500
 bgp router-id 192.168.1.101
 network 192.168.1.0/24
 neighbor fc00:192:168:1::1 remote-as 501
 neighbor fc00:192:168:1::1 ebgp-multihop 255
 neighbor fc00:192:168:1::1 timers 60 180
!
 address-family ipv6
 network fc00:192:168:1::/64
 neighbor fc00:192:168:1::1 activate
 exit-address-family
 exit
!
ip forwarding
ipv6 forwarding
!
line vty
!
end

Let me know if you need anything else. I’m working to fix my CI to correctly detect issues like these.

Hmm. I can't reproduce this. It works for me between 2 Quaggas.
