Steven,
Those address are the multicast address used for the RP and the mapping
agent.
Specifically 224.0.1.39 is for Cisco-RP-Announce used by the mapping agents
to learn about all candidate RPs
and 224.0.1.40 is for Cisco-RP-Discovery and is used by all PIM routers to
discover from the mapping agent the address of the RP.
