Issuing the show ip ospf database command will show you a summary of the database; however, to obtain details you must use a keyword with the command, such as router, network, summary, or external.

The following commands are available to verify OSPF configurations:

show ip route – displays known routes and from which protocol the routes were discovered for all routing protocols.
show ip ospf – displays the number of times the SPF algorithm has run and the default Link State Update (LSU) interval.
show ip ospf database – displays the router ID, the OSPF process ID, and the contents of the topological database.There is no show ip ospf topology command.The show ip ospf [process-id] command can be used to view the number of times the SPF algorithm has been executed, but not to view the database.The show ip ospf border-routers command display the ABRs and the routes to them, but not the contents of the database.
