Which command allows you to confirm that OSPF v. 3 Router IDs are unique between two routers?

show ipv6 ospf interface
show ipv6 ospf database
show ipv6 ospf
show ipv6 route

The correct answer is: show ipv6 ospf

The command that allows you to confirm that OSPF version 3 Router IDs are unique between two routers is the command to display OSPF information. Using the command shows relevant OSPF configuration and status information, including the Router ID for OSPF v3. In an OSPF network, each router must have a unique Router ID to prevent routing issues that can arise from ID conflicts. When you execute this command, it will list out the OSPF routers along with their respective Router IDs, enabling you to verify their uniqueness. Commands that focus on interfaces or routing tables might provide some OSPF-related details, but they do not provide the specific information needed to verify the uniqueness of Router IDs across different routers as comprehensively as the chosen command does.
