still having any problems with zebra and OSPF.

is anybody using bird to intercommunicate with zebra in a pointopoint link?

bird is connected to the zebras but i cant see any route coming from bird to zebra.

(sorry if this is a FAQ but i am new to the list and i havent seen an archive)

Zebra should communicate with BIRD over PTP. (The only known problem is with virtual link over unnumberd, but that is problem of OSPF design.)

So there could be some bug in routing table calculation (probably next hop) of zebra of a bug in LSA export in BIRD. Can you give me more information?

BIRD: show ospf neighbors, show interfaces, show ospf interfaces, show ospf, show route count

Zebra: show ip ospf neighbors, show ip ospf lsa <routerid>

(Use both routerids: of BIRD and routerid of Zebra)

I hope, I can help with such information.

Hello all! while trying to comunicate zebra and bird in a tunnel (pointopoint) conection, all the time bird keeps saying that: Sep 15 21:06:20 bell bird: Bad OSPF hello packet from 172.16.72.157 received: bad netma sk 0.0.0.0. after looking at hello.c i have commented the return after the log message. and bird is working really fine. What this error really means? is it a bird or a zebra issue? -ramon-
