LSA MAX age timer

By default, each OSPF LSA is only valid for 30 minutes. but when I have checked into real scenario I found
it shows 2040 sec which is 34 min.

Can we set LSA validity or its something else which took extra 4 min ?

Hi Ajay,

The max age of an LSA is 60 minutes so that’s why you still see the LSA in the LSDB. The refresh time (by default) is 30 minutes so for some reason, it seems your neighbor didn’t refresh this LSA.
