When I do "show ip ospf database" the advertising router is shown as 1 hr and not the Router Id of the router that advertised it.
The reason I have looked at this is there is a route being advertised that is in the Database but not in the routing table of this router.
Below are the outputs:-
Link ID ADV Router Age Seq# Checksum Link count
10.204.36.0 lhr 1367 0x80000965 0xCE9B
10.204.36.1 lhr 1367 0x80000965 0x1234
