Can someone explain the meaning of the output below. As soon as I configured
r2 as an RP with loopback 0 interface. I understand little about (*,
224.0.1.39) and (*,224.0.1.40) as the multicast address for announce and
discovery methods, but why in the middle it is using loopback as a source with
224.0.0.39.
Thanks
