Usage Guidelines

Usage Scenario

To implement the communication between a device and a device that supports auto-RP, run the auto-rp listening enable command to enable the auto-RP listening function on the device. The auto-RP listening function enables the device to receive auto-RP advertisement and discovery messages and learn RP information from the discovery messages.

Configuration Impact

After receiving an auto-RP advertisement message or discovery message, the device analyzes the source address of the message and then performs a reverse path forwarding (RPF) check based on the source address.

If the RPF check fails, the device discards the message; if the RPF check succeeds, the device forwards the message to other PIM neighbors.

Example
