I have test lab -- two OSPF routers, Bird 1.6.4: A, B.
2 areas defined: 0.0.0.0, 0.0.0.1. Export "all".
When rfc1583compat is Off I observe default route gets propagated via area 0.0.0.1 in despite its interfaces have higher costs than area 0.0.0.0's have.
Turning rfc1583compat On changes it to expected behaviour: interfaces costs are respected again.
Bug or am I missing some piece of OSPF knowledge here?
Hi
I think it is correct. In OSPF, intra-area paths using non-backbone areas are preferred over shorter backbone or inter-area paths. See RFC 2328, section 16.4.1.
And even higher interfaces costs shouldn't affect it? O_o -- End of message. Next message?
