I've got the problem: I'm trying to reditribute lo-address-es to ospf nssa area: Do you really need such redistribution? Much better thing to do is just adding interface "lo1" { stub; }; to appropriate area. Yes, I really need so -- at production environment part of them must be advertised as NSSA N1 and others as NSSA N2. Okay, there is a small bug in bird preventing actual errors to come up. Patch attached.
Real error is: bird: ospf1: Cannot find forwarding address for NSSA-LSA 81.19.94.167/32 Actual problem with redistribution resides in the following: when ospf comes up it interpretes all its active interfaces as interfaces with DOWN state. Interfaces with DOWN state are skipped on forwarding address lookup (we need to do this since P-bit is set). As a temporary workaround you can do the following: * apply attached patch (it is simple "sed -I'' s/log(L_ERR,/log(L_ERR/") * do birdc -c 'restart direct1' several seconds after bird is started.
My understanding was that OSPF NSSA does not work in bird. I'd love to be told I'm wrong! bird supports NSSA since 1.3.3
