When I am trying to create BGP session with Router A to Router B the IPv6 session is not getting established.
In Router A, i have created the session in Global routing table and in Router B, i have used VRF. For IPv4 and IPv6 Session from Router a, i will be only advertising default route using default-originate.
After removing the default-originate, the session is getting etsablished
In router B, we could observe the below logs
RP/0/RP0/CPU0:2022 Mar 14 03:03:54.430 JST: bgp: %ROUTING-BGP-5-ADJCHANGE_DETAIL : neighbor 240b:c0e1:2550::2111:1:6a Down - BGP Notification sent, illegal network (VRF: A ; AFI/SAFI: 1/1) (AS: 12345)
You mention ipv4/ ipv6 bgp peering but you dont show any ipv4 neighbour statements
Regards default route- are you saying when you remove an ipv4 default route thr bgp ipv4 peering establishes?
Note by design bgp peering will not establish if you are try to peer to a rtr using just a default route.
