Why do routes appear in the ospf database but not in the routing table?

The output of cisco outper interpreter said:

=====================================================================

SHOW IP OSPF DATA SUMMARY NOTIFICATIONS (if any)

=====================================================================

OSPF Process Id: 1 (Router ID: 172.16.6.6)

Area 1

WARNING: Routing manager has not attempted to install Link State Advertisements

(LSAs) from Area 1 with the following IDs into the routing table.

172.16.2.0

This can indicate connectivity problems between nodes or an OSPF routing

database defining many (sub-optimal) alternative routes. (This can be a

normal condition in a partially or fully-meshed network containing links

with widely varying bandwidths.)

TRY THIS: Confirm appropriate connectivity across the network.

REFERENCE: For more information see Why Do Routes Appear in the OSPF

Database But Not in the Routing Table in a Frame Relay Environment?

Who can help to explain, what is "an OSPF routing database defining many (sub-optimal) alternative routes. "? how to verify & solve it ?

thanks in advance.

Re: Why do routes appear in the ospf database but not in the rou

Of course, I have read the doc. of "Why Do Routes Appear in the OSPF database But Not in the Routing Table?". But I am sure my network has NO connectivity problem.

Re: Why do routes appear in the ospf database but not in the rou

Hi,

Once I had the same problem. I have interconnected two routers - Cisco 2610 and IBM 2212. Routes were in OSPF databases on both routers, but did not show in routing tables... I did not have time to troubleshoot that, but now I will try to set-up a similar environment and try once again to debug.

Check your network types make sure they match.I had a problem once where the hello and dead timers matched but the network timers did not and it showed in my database not my routing table.
