Usage Guidelines
Usage Scenario
The auto-RP listening function enables the device to receive auto-RP announcement and discovery messages and learn RP information from the messages. After receiving an Auto-RP Advertisement or Discovery message, the device obtains the source address of the message, and then performs reverse path forwarding (RPF) check based on the source address. If the RPF check fails, the device discards the packet. If the RPF check succeeds, the device forwards the packet to other PIM neighbors.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
