When converged, all the routers in the network shown above will know about the 192.168.5.0/24 network. If RouterD looses connectivity to 192.168.5.0/24, it will remove the route to that network from its routing table. When RouterC receives the next periodic update from RouterD, it will know that the route to 192.168.5.0/24 is lost, and will remove it from its routing table. At this stage, RouterA and RouterB still think that 192.168.5.0/24 is reachable via RouterC.
