What command would you use to list OSPF adjacency information?

The correct command to list OSPF adjacency information is particularly focused on retrieving the OSPF protocol data directly relating to router link-state advertisements. The command retrieves information about the OSPF router link-state advertisement (LSA) database, which contains details regarding the OSPF topology, including neighboring routers’ states and their link information.

When examining the OSPF process, understanding the link-state database is crucial because it allows you to analyze and confirm existing OSPF adjacencies or the state of the OSPF network. By detailing router LSAs, this command provides insights into both the OSPF neighbors and their statuses, thereby confirming adjacency setups.

In contrast, the command that relates to BGP neighbors focuses on the Border Gateway Protocol (not OSPF), thus making it irrelevant for OSPF adjacency checks. The command to configure Fortiguard is entirely unrelated to OSPF functionality. Lastly, while the diagnostic command provided does pertain to OSPF, it is aimed more at enabling additional diagnostic features rather than directly listing the adjacency information that you would find in the OSPF LSA database. This specificity in data retrieval is what identifies the correct command for the task at hand.
