Which statement describes the correct approach to verifying OSPF neighbors?

• A. Neighbors should be configured manually only.
• B. Neighborhoods do not need to be present.
• C. Check that expected OSPF neighbors are present.
• D. OSPF neighbors are irrelevant.

Answer: (C)

Verifying OSPF neighbors focuses on confirming that the routers you expect to form adjacencies with actually appear as neighbors. OSPF discovers neighbors by exchanging Hello packets on each interface, and a neighbor relationship only forms when parameters match—same area, network type, authentication if configured, and compatible hello and dead intervals. By checking the neighbor table and ensuring the expected neighbors are present and in the correct state, you validate that the network topology will exchange LSAs properly and function as intended. If an expected neighbor is missing or not in the right state, it points to a misconfiguration or connectivity issue, such as mismatched area IDs, incorrect IP addressing, or timer mismatches. To perform this check, review the OSPF neighbor list and interface status to confirm which neighbors have formed.
