    问答题
    Auto RP mapping agent 是什么,224.0.1.39 是起什么作用?

    正确答案: Mapping agent is the router that make decision which router in the multicast domain is RP. Mapping agent receives the RP announcement messages from candidate RPs and arbitrates conflicts. The RP mapping agent then sends the consistent group-to-RP mappings using discovery messages to all other routers by dense mode flooding.
    The multicast address 224.0.1.39 is used by Candidate-RP to send RP-announce message as the destination IP address, and the mapping agent is listening for the address.
