i have configured ospf on a two routers. the strange thing (seems to me anyway) is, when i type sh ospf nei i get a network ID of: 99.168.1.3 which is a loopback interface I have configured. The network should be
192.168.1.0, am i missing something?thx,
Your RID (Router ID) will be the highest IP address of any loopback interface configured. If no loopback interface configured then the highest IP address of any physical interface will be your RID.
The Router ID is always the highest IP-address on the router, or, if present, the IP adres of the loopback interface. It's normal.

You could explictly define your router id.
Router#config t Router(config)#router ospf XXX Router(config-router)#router-id xxx.xxx.xxx.xxx
I concur, and I would add that you 'should' explicitly defne what the router-id is. Why leave it to aristocracy. Control your routers before they control you.
