Which command is used to verify OSPF interface settings?

1. #show ip ospf

2. #show ip ospf interface

3. #show ospf status

4. #debug ospf interface

The correct answer is: #show ip ospf interface

The command used to verify OSPF (Open Shortest Path First) interface settings is the one that provides detailed information regarding the OSPF configuration and status at the interface level. Utilizing the command that explicitly states "oshp interface" delivers the necessary insight into how OSPF is functioning on a particular interface. When implemented, this command presents key details such as the OSPF interface state, network types (e.g., point-to-point or broadcast), timers, and the OSPF neighbor status. This granularity of information is vital for troubleshooting and optimizing OSPF performance on the network interfaces. The alternative commands serve different purposes. For instance, while the command detailing overall OSPF activity provides a broader view of the routing protocol's function across the entire device, it does not drill down into specific interface characteristics. Similarly, commands focused on debugging are designed more for troubleshooting and real-time monitoring rather than providing an instantaneous configuration overview. This helps clarify the importance of selecting the appropriate command for OSPF interface verification.
