I have a problem where a route entry is not appearing in the ospf database. My understanding was that the database would populated with all entries to a particular destination and would then install the preffered route into the routing table.
I have a problem at the moment where the ospf database is not being populated with all possible entries.
Is there an easy way to troubleshoot this issue by running some ospf debug commands?
I have attached some sh commands, the entry in question is the 10.9.0.0/16, I see 2 entries but I should see a 3rd via 22.214.171.124 which I currently don't.
The ospf area for vlan 412 is just a standard ospf area (area 60).
The router 126.96.36.199 learns the 10.9.0.0/16 route from another ospf process and is redistributed into the ospf 61 process connecting to vlan 412, there is no summary of this on this router, that is the route it learns, this route would originally come from bgp then into ospf
No, you shouldn't expect to see 3 LSAs on 10.236.32.4. The situation is exactly as I was pointing out.
On router 188.8.131.52, the external LSA from process 61 is installed in the RIB, which prevents the external LSA from process 60 to be installed in the RIB and therefore to be redistributed in process 61. This is the drawback of having separate process and doing redistribution between them.
