Displaying the IPv4 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 partical-sc [hostname |
group_number]
This example shows how to display the IP multicast routing table:
Router# show ip mroute 230.13.13.1

The RPF-MFD flag indicatesthat the flow is completely switched by the hardware. The H flag indicates
Note
the flow is switched by the hardware on the outgoing interface.
