Which command allows you to view the multicast routing table?

The command that allows you to view the multicast routing table is "show ip mroute." This command is essential for network engineers because it displays the multicast routing table entries currently in use on a router. The multicast routing table contains information about the sources of multicast traffic, the distribution trees that are established, and the interfaces through which the multicast traffic is being forwarded.

Understanding the multicast routing table is crucial for diagnosing multicast connectivity issues and optimizing the flow of multicast data through the network. By using "show ip mroute," you can identify which multicast groups are being routed, the sources of the multicast streams, and the downstream interfaces where multicast traffic is delivered.

While other commands, such as "show ip multicast-routing," might seem relevant, they typically provide different sets of information regarding multicast configurations or PIM (Protocol Independent Multicast) neighbor relationships, rather than the actual routing table for multicast traffic.
