When link-state information reaches the maximum age on a router, the router will flood that information to its neighbors.

When a router detects that any of its link-state information has reached the maximum age, it will request a new update from the source router.

Aging helps ensure that links, which are no longer part of the topology, will eventually get removed from the LSDB.

The age value is updated as the information is flooded throughout the network and when it is in the LSDB.
