Yes, OSPF is one of those nifty protocols that allows you to peer
between 2 IPs in different subnet.
Does anyone know if thats true with RIP and EIGRP? I think RIP can be
configured to disable the source address check but what about EIGRP?
Joseph Saad - Can you elaborate on using interface level ospf versus
network statement?
Thanks
