Configuring the Source RP Address of the SA Message

Configuring the Source RP Address of the SA Message


In the anycast RP application, you need to configure rendezvous points (RPs) on two or more devices in a Protocol Independent Multicast Sparse Mode (PIM-SM) domain, assign the same IP address to these RPs, and set up MSDP peer relationships between these devices. An MSDP peer performs the RPF check on a received SA message and then discards the message if the addresses of the local RP and the remote RP are the same. Therefore, you need to specify a logical RP address for the SA message on the device on which anycast RP is to be configured.


  1. Run:


    The system view is displayed.

  2. Run:

    msdp [ vpn-instance vpn-instance-name ]

    The MSDP view is displayed.

  3. Run:

    originating-rp interface-type interface-number

    The address of the logical RP interface is set as the source RP address for the SA message.

    The interface functioning as a logical RP cannot be an actual RP interface. It is recommended that you configure the address of the MSDP peer interface as the logical RP address.
