A company has two routers RTA and RTB in their HQ. RTB is connected to remote office over a slow serial link. The remote office network is 192.168.1.0/24. If this link breaks down, both ISP and RTA will lose their reachability to 192.168.1.0/24 and possibly enter into a looping route. Enter the commands on RTA to prevent this looping. You are using OSPF in this instance.
