Issue With Cisco 2620XM Router & OSPF

I have a Cisco 2620XM Router, running ver. 12.2 (7r). I have OSPF connected, however the OSPF routes are not populating in the sh ip route display. The  neighbor relationship is established. The sh ip ospf database does display the other routers running ospf, however only connected (C) and static (S) routes appear.

What am I missing?

Issue With Cisco 2620XM Router & OSPF

You have not given us much detail to work with so it is difficult to know what the problem is. Can you post the output of show ip interface brief, the configuration of ospf and the output of show ip ospf interface, the output os show ip ospf database and the output of show ip route? If we had that information we might be able to give you better answers.

Without seeing the detail that I requested I will make a guess that the router has connected routes and static routes that are the same as the routes advertised by the ospf neighbor. The admin distance of connected routes and of static routes are more attractive than the admin distance of ospf routes and if there are static or connected routes that are the same as the ospf routes then the ospf routes do not get into the IP routing table.

Thanks for the additional information that I requested. It is  somewhat helpful but is not enough for me to figure out what the problem  is. It does show that you have OSPF neighbor and that the OSPF data  base does have some prefix entries which look like they should go into  the routing table, but the routing table does not have OSPF routes.  There must be some other aspect that we have not yet recognized that is  causing this. I can think of a few things which could cause this symptom  such as changing the administrative distance of OSPF or applying a  distribute list on routing updates. But am not sure what it might be in  this particular case. Perhaps you could post the entire configuration of  the router?
