Displaying the current RP set

The BSR sends periodic RP updates to all C-RPs in the domain. These updates include the set of multicast group data configured on and reported by all C-RPs in the domain. This data does not include any static RP entries configured on any router in the domain. (To view the static RP-set information for any static RPs configured on a particular router, you must access the CLI of that specific router.)

Syntax:


show ip pim rp-set [learned | static]

Without options, this command displays the multicast group support for both the learned C-RP assignments and any statically configured RP assignments.

learned: Displays only the learned C-RP assignments the router has learned from the latest BSR message.
static: Displays only the statically configured RP assignment(s) configured on the router.
