Displaying the IP Multicast Routing Table
The show ip mroute command displays the IP multicast routing table.
To display the IP multicast routing table, perform this task:
Command
Router# show ip mroute [hostname | group_number]
This example shows how to display the IP multicast routing table:
Router# show ip mroute 230.13.13.1
