[zebra 23081] Re: zebra, ospf, ping and traceroute problem

Hi Daniel,

you said you set up couple of Linux machines but showing us just
config and outputs of r2. So it is hard to guess what is wrong. Why
are you using ip ospf network command on interface, what kind of
network between neighbours are you useing? Can ypu provide us with sh
ip ospf neigh command and respective config of neighbors?

Regards, Michal
