What must be configured to restore OSPF neighbor adjacency?
In Open Shortest Path First (OSPF), matching MTU values across interfaces is crucial for establishing and maintaining neighbor adjacencies. If the MTU values do not match, the routers may not be able to properly exchange database description packets, leading to the failure of forming a neighbor relationship. The retransmissions and eventual failure to establish OSPF adjacency shown in the exhibit are indicative of an MTU mismatch. Therefore, to restore OSPF neighbor adjacency, the MTU values must be matched.
