What command can be used to view OSPF neighbors?

To view OSPF neighbors, the command "show ip ospf neighbor" is used. This command provides detailed information about the OSPF neighbors that a router has discovered through OSPF hello packets. The output includes important information such as the neighbor's router ID, state (like full or 2-way), the dead interval, and the interface through which the neighbor is connected.

This command is specific to OSPF and thus provides relevant details about the OSPF adjacency state, which is crucial for troubleshooting and understanding the OSPF routing environment. Understanding the relationships between routers in an OSPF network helps in network design and monitoring.

In contrast, "show ip route" provides information on the entire routing table and does not specifically target OSPF neighbors. The command "show ip neighbor" is not a valid command for OSPF as it doesn't specifically relate to OSPF's operations. Lastly, "display ospf neighbors" is not a command used in Cisco IOS; the correct syntax aligns with the "show" command structure.
