Which command displays the OSPF v3 interfaces assigned to a particular area?

1. #show ipv6 ospf interface

2. #show ospf interface

3. #show ipv6 ospf interface brief

4. #show ipv6 ospf neighbor

The correct answer is: #show ipv6 ospf interface

The command that displays the OSPF v3 interfaces assigned to a particular area is indeed the command that begins with "show ipv6 ospf interface." This command is specifically designed for OSPFv3 (Open Shortest Path First version 3), which operates over IPv6 networks. When executed, it provides a detailed output that includes information about the interfaces that OSPFv3 is using, including the state, costs, and area assignments of each interface. Using this command is crucial for network professionals who need to verify which interfaces are participating in OSPFv3 and how they are configured in terms of their respective areas. The output helps in troubleshooting and ensuring that the OSPFv3 routing protocol is correctly set up to enable efficient routing over IPv6 networks. The other choices offer different functionalities and outputs but do not specifically address the need to display OSPFv3 interfaces within a designated area. For instance, the command for a brief output may not provide full details on area assignments, while commands focused on neighbors или general OSPF statistics would not yield information about the interfaces themselves.
