Configuring an Originating Address other than the RP Address
You can allow an MSDP speaker that originates an SA message to use the IP address of the interface as the
RP address in the SA message by changing the Originator ID. You might change the Originator ID in one of
these cases:
• If you configure a logical RP on multiple Device in an MSDP mesh group.
• If you have a Device that borders a PIM sparse-mode domain and a dense-mode domain. If a Device
If both the ip msdp border sa-address and the ip msdp originator-id global configuration commands are
configured, the address derived from the ip msdp originator-id command specifies the address of the RP.
Follow these steps to allow an MSDP speaker that originates an SA message to use the IP address on the
interface as the RP address in the SA message:

borders a dense-mode domain for a site, and sparse-mode is being used externally, you might want
dense-mode sources to be known to the outside world. Because this Device is not an RP, it would not
have an RP address to use in an SA message. Therefore, this command provides the RP address by
specifying the address of the interface.
