Which command is used to verify OSPF neighbor relationships?

• A. show ip ospf neighbor
• B. display ospf neighbors
• C. show ospf connections
• D. view ospf neighbors

Answer: (A)

The command used to verify OSPF (Open Shortest Path First) neighbor relationships is "show ip ospf neighbor". This command provides detailed information about OSPF neighbors that a router has established in the network. Specifically, running this command displays the state of each OSPF neighbor, including their Router ID, priority, and the status of the adjacency (such as Full or 2-Way). Understanding OSPF neighbors is crucial because they are the first step in forming OSPF routes. OSPF uses neighbor relationships to exchange routing information, ensuring that routers can communicate effectively to maintain a consistent view of the network topology. By verifying these relationships, network administrators can troubleshoot connectivity issues, monitor OSPF operation, and confirm that routers are successfully forming adjacencies. Other options do not represent valid commands in Cisco’s IOS for checking OSPF neighbor relationships. The terminology used in those alternatives does not align with Cisco commands, making them unreliable for this purpose.
