If an OSPF router goes down, and it was the gateway to one or more subnets, how do other routers in the network decide to remove their routes to those subnets.
what you'll learn from this video:
If a router goes down, other routers cannot prematurely age the LSAs that the now-down router was originating. But, if the router that goes down was the only gateway to one or more subnets, the routes to those subnets need to be withdrawn. This is achieved because neighbors of the now-down router will send out new versions of their LSAs, that no longer have connections to the now-down router.
