BGP IPv6 error
-
Hello,
I'm using the FRR package to do BGP. The BGP IPv6 session does not come online and appears as V 4. I think this is not normal. Is it possible for FRR to have a bug with IPv6?

Was this working and then failed?
Has it ever worked with pfSense/FRR?
Has it ever worked with anything?
-
Yes, with IPv4 the BGP session is online and working. The BGP session over IPv6 never worked.
-
BGP on the other side is working.
-
With IPv4 I can see traffic in the GRE tunnel, with IPv6 no traffic appears.
-
Do you see states opened for the BGP traffic? Do you see blocked traffic in the firewall log?
-
I see BGP states with IPv4 but not with IPv6. I don't see blocked traffic in the IPv6 firewall logs for BGP. I think the FRR is not sending IPv6 packets to the network.
-
So you see it opening states outbound to the configured neighbour IPv4 address?
-
Yes, I see the BGP session opening sates via IPv4 but not IPv6.
