Hello. I'm trying to reproduce a config which worked in bird1.6 (bird6) I need to announce the IPv4 and IPv6 loopback addresses of lo:1 

protocol direct direct_lo {         interface "lo";         ipv4;         ipv6; }

protocol ospf v3 OSPFv3_backbone {     debug all;     ipv6 {         export where proto = "direct_lo";     };     area 0 {         networks {             ...         };         interface "ens20" {             ...         };     }; }

I don't know if it's normal but I have no prefixes in :

bird> show protocols all direct_lo Name       Proto      Table      State  Since         Info direct_lo  Direct     ---        up     16:16:59.087     Channel ipv4     State:          UP     Table:          master4     Preference:     240     Input filter:   ACCEPT     Output filter:  REJECT     Routes:         0 imported, 0 exported, 0 preferred     Route change stats:     received   rejected   filtered    ignored   accepted       Import updates:              0          0          0          0          0       Import withdraws:            0          0        ---          0          0       Export updates:              0          0          0        ---          0       Export withdraws:            0        ---        ---        ---          0   Channel ipv6     State:          UP     Table:          master6     Preference:     240     Input filter:   ACCEPT     Output filter:  REJECT     Routes:         0 imported, 0 exported, 0 preferred     Route change stats:     received   rejected   filtered    ignored   accepted       Import updates:              0          0          0          0          0       Import withdraws:            0          0        ---          0          0       Export updates:              0          0          0        ---          0       Export withdraws:            0        ---        ---        ---          0

and no route exported to OSPF : bird> show route export OSPFv3_backbone bird>

What am I doing wrong ? Regards 

Hello, If I remember well, ospfv3 needs to have an address in fe80::/64 on an interface to get addresses from it. lo usually does not have it, you should add one. Regards, -- Bastien
