To find out if multicast routing is active, which command should you use?

To determine if multicast routing is active, using the command that displays IPv6 multicast information is appropriate because multicast routing can differ between IPv4 and IPv6. The command retrieves the status of multicast routing protocols and their configurations specifically in an IPv6 context, which is essential for understanding how multicast traffic is managed in IPv6 networks.

In environments where IPv6 is deployed, verifying multicast settings specific to IPv6 helps network administrators ensure that multicast routing is functioning as expected and that multicast traffic can flow properly in the IPv6 infrastructure. This is critical for applications that utilize multicast, such as video streaming or certain types of data distribution, which rely on both proper routing and network configurations.

Other commands, while useful for different aspects of networking, do not focus specifically on multicast routing in an accurate manner. For example, one command would typically provide a general overview of the routing table, while another may display the current running configuration of the router, which may not contain multicast-specific details. In contrast, accessing IPv6 multicast information gives precise insights into the multicast routing status for that protocol.
