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 Router B with
that displayed on Router D, you can see that Router B acts now as the RP for Source 1 and Host A.

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