  1. D

    Candidate RPs send RP Announce messages on the 224.0.1.39 group. These messages contain a list of multicast groups the device would like to be the RP for. Mapping Agents listen to 224.0.1.39 in order to collect the RP information from all candidate RPs and send RP Discovery Messages on the 224.0.1.40 group. The RP Discovery Messages destined to 224.0.1.40 contain the best elected RP-to-group mapping information from Mapping Agents.
