OSPF Net Links

[peter.mark]

I changed an IP address on FastEthernet interface of a 3640 but the interface address doesn't appear under

OSPF database Net Links? I tried clearing the OSPF process and reloading the router. There is a route in the routing table and everything seems to be working. Is this an OSPF issue or something that can be ignored?

Hello,

what does your OSPF network look like ? Remember that Net Link States are only generated by the DR. Do a ´show ip ospf neighbor´ on your router to check if you have a full adjacency with the DR (and the BDR).

Georg,

This is a point-to-point connection. The adjacent router state is full. That router also does not have the interface address in it's Net Link table.

Hello Pete,

as Mark mentioned, on a point-to-point link, there are only two routers and no DR, hence no net links.

A network link is only produced when there is more than one router on the network. If there is only one router attached to the LAN, the LAN will be advertised as a stub network link in that router's router LSA.
