A network administrator is troubleshooting an OSPF problem that involves neighbor adjacency. What should the administrator do?

To establish and maintain OSPF neighbor adjacencies, it is crucial that the hello and dead interval timers match across all OSPF routers in the same area. OSPF uses these timers to determine how frequently it sends hello packets to its neighboring routers and how long it waits to declare a neighbor as down.

If the hello and dead interval settings do not match between neighboring routers, adjacent routers will not recognize each other as neighbors, leading to communication failures. This mismatch prevents OSPF from establishing a full adjacency, which is necessary for routing information to be successfully exchanged.

Thus, ensuring that the hello and dead interval timers are consistent across all participating routers is essential for troubleshooting OSPF adjacency issues effectively.
