What command is used to list details about type-a LSAs?

The command that is used to list details about type-a LSAs is one that specifically targets the OSPF (Open Shortest Path First) database. Type-A LSAs, which are defined by the OSPF protocol, refer to router LSAs that contain information about routers within an OSPF area.

The command that provides the details of such LSAs directly accesses the OSPF database, allowing an administrator to view information about the routers, their interfaces, and the network topology. Therefore, by executing the command to list router LSAs in the OSPF database, one can retrieve crucial information about the operational state and configuration of routers participating in OSPF.

Other commands mentioned serve different purposes:

• One focuses on BGP neighbors, which is unrelated to OSPF and does not retrieve LSA information.

• Another command pertains to IP router OSPF status but does not narrow it down to LSAs specifically.

• The last option is for clearing BGP sessions, which again does not relate to the OSPF LSA context.

This specificity in targeting the OSPF database is why the command for listing router LSAs is the accurate choice.
