Hi all, curious if anyone has run into issues with IPv6 uRPF on NCS5500 and/or XR 6.2.3? I have an interface where I added:
Ipv4 verify unicast source reachable-via any ipv6 verify unicast source reachable-via any and immediately lost my ability to talk to a BGP peer connected to it using a local /126 range; no ping, tcp, etc. There’s obviously a route in FIB given it’s connected and up, but I did check. The same issue does not occur with the remote IPv4 peering address on a /30 net, suggesting uRPF for ipv4 doesn’t have the same bug.
