What does the command #show ip ospf display?

1. OSPF neighbors and their states

2. OSPF process information, including areas and interfaces

3. All OSPF database entries

4. Real-time OSPF adjacencies

The correct answer is: OSPF process information, including areas and interfaces

The command #show ip ospf provides detailed information about the OSPF (Open Shortest Path First) process running on a router, which includes aspects such as the OSPF router ID, the various areas that the router is a part of, and the interfaces on which OSPF is enabled. This command gives network administrators insight into the configuration and operation of OSPF within a specific routing domain, showing how OSPF is structured and how it interacts with different areas and connections on the router. Understanding this command is essential for network troubleshooting and management, as it helps in verifying the proper functioning of OSPF and ensuring that routers are correctly configured to communicate with one another through their respective OSPF processes. This context makes it clear why the choice stating OSPF process information, including areas and interfaces, is correct.
