Configuring the Source RP Address of the SA Message
Context
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.
Procedure
- Run system-view
The system view is displayed.
- Run msdp [ vpn-instance vpn-instance-name ]
The MSDP view is displayed.
- 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.
