[c-nsp] Re: OSPF distribute problem

[M.Palis]

Hi Oli

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. 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

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.

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. ----- Original Message -----

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.
