To check that interfaces are not set to passive on an OSPFv3 network, which command should be utilized?

1. #show ipv6 ospf interface

2. #show ipv6 routing status

3. #show ipv6 link-status

4. #show ipv6 ospf database

The correct answer is: #show ipv6 ospf interface

The selected command to check that interfaces are not set to passive on an OSPFv3 network is indeed the correct choice. This command provides detailed information about each interface that is participating in the OSPFv3 process, including the operational status of those interfaces. Specifically, it displays whether an interface is set to passive or active for OSPFv3, which is crucial for ensuring that OSPFv3 is functioning properly and that routing updates can be exchanged between routers on the network. Other options may provide useful information but do not specifically address the requirement of checking for the passive status of interfaces in an OSPFv3 configuration. The routing status command typically gives a summary of the routing table, the link-status command relates to the physical layer connectivity, and the OSPF database command is oriented towards understanding the routing information database's content rather than the operational state of the interfaces. Thus, to directly check for passive interfaces, the first command is the most appropriate choice.
