Network not in OSPF Database but showing up in routing table as

Hi Team,

I am seeing something that doesn't look like normal behavior. I am learning
a route via OSPF (as can be seen from "show ip route" output) but when I do
"show ip ospf data" I cannot find an LSA for the network. The topology is
very simple, all routers are in area 0 and the route is being advertised
into OSPF natively (no redistribution).

R2#sh ip route 40.40.40.0
Routing entry for 40.40.40.0/24
  Known via "ospf 1", distance 110, metric 129, type intra area
  Last update from 155.1.0.5 on Serial0/0/0, 00:07:26 ago
  Routing Descriptor Blocks:
  * 155.1.0.5, from 150.1.4.4, 00:07:26 ago, via Serial0/0/0
      Route metric is 129, traffic share count is 1
R2#sh ip ospf data

Now on the router that is advertising the route:

R4#sh ip int b

Is anybody aware of this behavior? Is this normal? Am I missing something?

Thanks for your input on this issue.
