To view the PIM routing information on the switches, use the display pim routing-table command.
When Source 1 10.110.5.100/24 sends multicast data to multicast group G 225.1.1.1, Host A
joins multicast group G. By comparing the PIM routing information displayed on Switch B with that
displayed on Switch D, you can see that Switch B acts now as the RP for Source 1 and Host A.
# Display PIM routing information on Switch B.
