Which command can you use to view the link-state PDUs?

The command you would use to view the link-state PDUs is "show isis database detail." This command provides a comprehensive view of the Intermediate System-to-Intermediate System (IS-IS) routing protocol's database, which includes detailed information about the link-state Protocol Data Units (PDUs) each router has in its link-state database.

When you execute this command, it displays information such as the originating router, the type of PDU, and the metric for each link. This is crucial for understanding the topology of the network and how IS-IS is managing routes within that topology. The detail provided by this command allows network engineers to verify which routers have sent updates, the state of their interfaces, and any other pertinent information regarding how IS-IS is operating in the network.

In contrast, other options provide different types of information. For instance, "show isis route detail" gives details about routing entries and not specifically about the link-state database. "Show isis adjacency" focuses on the status of IS-IS neighbors and their adjacency state, while "show isis spf results" displays the results of the Shortest Path First algorithm but does not provide direct details of the PDUs themselves. Each of these commands has its unique
