Specifying the RP Address Used in SA Messages

The default originator-id is the address of the RP that created the message. In the case of Anycast RP, there are multiple RPs all with the same address.

To use the (unique) address of another interface as the originator-id, use the following command.
Use the address of another interface as the originator-id instead of the RP address. CONFIGURATION mode ip msdp originator-id
