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 now acts as the RP for Source 1 and Receiver 1.
Source 1 registers with Switch B and Receiver 1 sends a join message to Switch B.
