Which command will display the OSPFv3 process number and associated areas?

1. #show running-config

2. #show ipv6 protocols

3. #show ipv6 ospf neighbors

4. #show ipv6 interface brief

The correct answer is: #show ipv6 protocols

The command that displays the OSPFv3 process number and associated areas is indeed the one indicated. With this command, you gain insights into the configurations and settings specific to the OSPF for IPv6. It allows you to see OSPF routing protocol parameters, including process ID, areas configured, and the interfaces that participate in OSPFv3. The other options provided serve different purposes. The running-config command displays the entire current configuration of the router, which will include OSPF settings but requires parsing through potentially a lot of output without focusing specifically on OSPFv3. The command that shows OSPF neighbors provides information about adjacent OSPF routers and their states, which is useful for troubleshooting neighbor relationships but does not include area information. The command that displays interface brief status gives an overview of IPv6 interfaces but does not convey any specific details regarding the OSPFv3 configuration or area associations. Thus, the command showing IPv6 protocols is correctly focused on providing the necessary OSPFv3 details.
