show ip ospf database

This command displays information about the link state database when OSPF is enabled for the specified virtual router. If no router is specified, it displays information for the default router. If you do not enter any parameters, the command displays the LSA headers for all areas. Use the optional areaid parameter to display database information about a specific area. Use the optional parameters to specify the type of link state advertisements to display.

Format show ip ospf [areaid] database [vrf vrf-name] [{database-summary | [{asbr-summary | external | network | nssa-external | opaque-area | opaque-as | opaque-link | router | summary}] [lsid] [{adv-router [ipaddr] | self-originate}]}]
