Which command will help you determine the origin of a route learned through OSPF in your routing table?

To determine the origin of a route learned through OSPF, the command that provides the most relevant information is the one that displays the OSPF database. The OSPF database contains information about all OSPF routes, including details such as their source, type, and any associated metrics. By examining the OSPF database, network administrators can trace back the origins of specific routes, understand which OSPF routers advertised them, and observe the link-state information related to those routes.

While other commands may provide useful routing information, they do not directly reference the origin as clearly or comprehensively as the OSPF database command does. For instance, the command that shows the route protocol OSPF focuses on the routing table and might not give in-depth details about the originating router or the specific OSPF advertisements. Similarly, viewing OSPF logs and other routing information can be beneficial for troubleshooting, but they don't provide the direct insight into the OSPF route origins like the database does. Thus, accessing the OSPF database is essential for tracing and understanding the source of OSPF-learned routes effectively.
