How can OSPF neighbors be verified?

The command "show ip ospf neighbor" is the correct method to verify OSPF (Open Shortest Path First) neighbors in a networking environment. When this command is executed on a router, it provides detailed output about the OSPF neighbors that the router has discovered. This includes essential information such as the state of each neighbor (e.g., Full, 2-Way), the interface through which the neighbor was discovered, and the router ID of each neighbor.

This command is crucial for network administrators as it helps confirm that OSPF adjacency has been established correctly between routers. It also assists in troubleshooting OSPF-related issues, such as misconfigurations, connectivity problems, or ensuring that neighbors are in the expected state.

The other options do not represent valid commands in this context. The first choice, while similar, is not formatted accurately for OSPF neighbor verification. The third choice does not correspond to a recognized command, and the fourth choice lacks the specificity needed to retrieve OSPF neighbor information.
