hi,

assume for some reason the LSDB was not synced with all OSPF routers in the area. How can we verify it? Is there a revision number like?

Hi Mohammed,

Show ip ospf database command can deliver you information about different OSPF link state advertisement and also help to examine the link-state database (LSD) and its contents.

Sequence filed in the output depicts that Link-state swq. number is old or duplicate LSA.

Hope it Helps..

Rate if it Helps.

Just add to Ganesh,

Adjacancy will not be established unless OSPF databses are synced.

"sh ip ospf database database-summary" command gives the number of routers and networks in OSPF database.

"sh ip ospf database network" (as Ganesh mentioned) shows the seq number of each LSA.
