The command you provided, which is used to check OSPFv3 interfaces that are currently passive, is indeed correct. The command “show ipv6 ospf interface INTERFACE” specifically displays detailed information about OSPFv3 interfaces, including their state and whether they are active or passive. This command will show relevant details such as the OSPFv3 neighbor status and metrics, which are essential for understanding the behavior of OSPFv3 on a router.

Other options address different aspects of network configuration or status. One might provide information about OSPF protocols more broadly, but not specifically about passive interfaces. Another could reveal neighbor adjacency, which is crucial in OSPF but doesn’t focus on the passive state of the interfaces. Lastly, the command that provides a brief summary of all IPv6 interfaces will not show specific OSPF configurations or states. Hence, understanding the particular function of each command helps in recognizing why the selected command is most appropriate for identifying passive OSPFv3 interfaces.
