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), Receiver 1 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 Receiver 1.

Receiver 1 has left multicast group G. Source 1 has stopped sending multicast data
to multicast group G. When Source 2 (10.110.6.100/24) sends multicast data to
G, Receiver 2 joins G. By comparing the PIM routing information displayed on
Switch B with that displayed on Switch D, you can see that Switch D acts now as
the RP for Source 2 and Receiver 2.
