What command displays detailed information about OSPF?

1. #show ip ospf

2. #show ip protocols

3. #show ip ospf database

4. #debug ip ospf packet

The correct answer is: #show ip ospf

The command that displays detailed information about OSPF is indeed the one that shows the OSPF process and its configuration details. This command provides essential information such as the OSPF router ID, OSPF area information, timers, and statistics related to OSPF neighbors and adjacencies. It's a vital command when troubleshooting or verifying OSPF operation within a network. While other commands can provide useful information related to OSPF, they serve different purposes. For example, one command focuses more on OSPF database contents rather than the overall OSPF configuration and operational status, while another command can be used for monitoring real-time OSPF packet exchanges but does not convey the configuration state. Similarly, another option gives insights into the overall IP routing protocols running on the device, including OSPF, but lacks the detailed focus specifically on OSPF.
