display ospf lsdb

Function

The display ospf lsdb command displays an OSPF Link-State Database (LSDB).

Format

display ospf [ process-id ] lsdb [ brief ]

display ospf [ process-id ] lsdb [ { router | network | summary | asbr | ase | nssa | opaque-link | opaque-area | opaque-as } [ link-state-id ] ] [ originate-router [ advertising-router-id ] | self-originate ] [ age { min-value min-age-value | max-value max-age-value } ^* ]

Parameters

Usage Guidelines

To check information about the LSDB, run the display ospf lsdb command. You can choose to view:

Brief information about the LSDB
LSAs of a specified type
LSAs of the originating device
Locally originated LSAs

The command output helps you troubleshoot OSPF faults.
