Hi All!
Hello
First, the HELLO packet ignored with "Bad OSPF hello packet from 1.0.0.1 received: options mismatch (0x12)." if i use the cisco default ospf configuration.
With "ip ospf lls disable" option everything is ok.
This is probably inappropriate options handling in BIRD, we will fix it.
Second, i advertise some alias IP from the pc to the cisco router, but if i remove the alias address from the interface some OSPF routes still present in the cisco router.
So i suppose the problem is just the route 192.0.2.0/24 ? I am not sure where it comes from. Could you send me output of command 'show interfaces' and 'show ospf state' on BIRD?
