Which command is used to display assigned interfaces to different OSPF areas?

1. #show ipv6 ospf interface brief

2. #show ipv6 ospf interface INTERFACE

3. #show ipv6 protocols

4. #show ipv6 neighbors

The correct answer is: #show ipv6 ospf interface brief

The command that displays assigned interfaces to different OSPF (Open Shortest Path First) areas is the one that provides a brief overview of all interfaces on the device and their current OSPF configuration specifics. By using this command, you can quickly ascertain which interfaces are associated with which OSPF areas, along with their status and relevant OSPF parameters. This brief view is valuable for network administrators as it allows for efficient troubleshooting and network monitoring. It simplifies the understanding of how OSPF is configured across various interfaces, showing, for example, whether the interface is in a designated area or if it is active and participating in OSPF routing processes. Other commands available in the context of OSPF may provide more detailed information about specific interfaces or protocols, but they do not give a comprehensive overview of all interfaces and their respective area assignments as effectively as the chosen command.
