Configuring a candidate RP
Configure a C-RP router to add it to the RP Set.

You can configure only one interface on a switch for multiple groups; that is, you cannot configure multiple interfaces for multiple groups.
Using the GroupMask value, you can configure a candidate RP for several groups in one configuration. For example, if you use a C-RP configuration with a GroupAddress value of 224.0.0.0 and a GroupMask of 240.0.0.0, you can configure the C-RP router for a multicast range from 224.0.0.0 to 239.255.255.255.
