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.
