Which command would you use to enable OSPF real-time debugging?

Enabling OSPF (Open Shortest Path First) real-time debugging is crucial for network administrators who need to troubleshoot OSPF routing issues effectively. The command that is utilized for this specific purpose is designed to provide detailed logging and output regarding OSPF processes as they occur within the network.

The correct command, which enables real-time debugging for OSPF, allows administrators to monitor OSPF events and changes, such as neighbor state changes, link cost adjustments, and route calculations. This level of detail is invaluable when diagnosing specific issues related to OSPF in a complex network environment. By using the specified command, you gain insights into the OSPF operations, helping to identify misconfigurations or performance issues that could impact routing functionality.

In contrast, other commands listed do not pertain to OSPF debugging. For example, some commands focus on different protocols like BGP (Border Gateway Protocol), which would not provide OSPF-specific debugging information. Others might involve accessing web filtering categories or general debugging commands that do not specifically enable OSPF monitoring. Thus, the chosen command effectively addresses the requirement for real-time OSPF debugging, making it the right option to select.
