Which command would you use to check the OSPF router ID of a neighboring router?

The command to check the OSPF router ID of a neighboring router is "show ip ospf neighbor." This command provides detailed information about OSPF neighbors and their current state. Among the output is the OSPF router ID of each neighbor, which is crucial for understanding the network topology and diagnosing OSPF-related issues.

Using this command allows network engineers to verify neighbor relationships, Router IDs, and the status of OSPF adjacencies, which are essential for ensuring efficient routing and troubleshooting OSPF configurations. The information retrieved can help determine if there are any issues with OSPF neighbor formation, such as mismatched configurations or network connectivity problems.

Other options would not provide the OSPF router ID. The command for interfaces focuses on interface configurations, the routing table command displays routes but not neighbor associations, and the version command provides information about the device's software and hardware but does not include OSPF specifics.
