I checked the documents. Problem is with the IOS since changing the IOS on the Cisco7400 the routes are inserted on the routing table of the C7513.
Ok, and did you find out if the RIB installation fails due to "incorrect" FA?
My configuration is simple. Just a C7513 and a C7401 connected via Ethernet and running OSPF between them. I am redistributing static router to ospf on the C7401. The static router appear on the ospf database of the C7513 but not on the routing table
sh ip ospf database | incl 192.168.1.1 192.168.1.1 192.168.2.1 131 0x80000023 0x00378C 0
Hmm, not enough data to tell.. We'd need to see "show ip ospf data external 192.168.1.1" and the config on the 7401.
sh ip route 192.168.1.1Routing entry for 192.168.1.0/24 Known via "static", distance 1, metric 0 (connected) Advertised by bgp XXX Routing Descriptor Blocks: * directly connected, via Null0 Route metric is 0, traffic share count is 1
static route to null 0 is on the C7513 for BGP purposes.
ack.
In case I change the IOS of the 7401 ro 122-4(B8) (and no changes on C7513) everything works fine but we are faceing some other issues with MTU which are solved by updading IOS.
Does the OSPF DB entry for this LSA differ in any way when comparing the different IOS on the 7401?

We are facing a problem with OSPF distribute routes. We have a C7400 routers where we redistribute some routes to the OSPF and then to a C7507 router. The C7507 router does not install the routes to the routing table. I check the show ip ospf database of the C7507 and the routes are existing there but not on the routing table. I believe that the problem is on the C7507 since we try various IOS on the 7400 and other routers can see the OSPF distribute routes that the C7400 redistributes.
Issues like this usually involve problems with the forwarding address in your Type-5 LSAs. Without knowing more about the topology, router configs, OSPF database and routing table outputs, it will be difficult to troubleshoot this further.
