Concept Guide

The Congured multicast group ranges are used by the BSR protocol to advertise the candidate RPs in the bootstrap messages.
You can congure the multicast group ranges as a standard ACL list of multicast prexes. You can then associate the congured group list
with the RP candidate.
NOTE: • If there is no multicast group list congured for the RP-candidate, the RP candidate will be advertised for all the
multicast groups.
To enable an RP to serve specic group of multicast addresses, perform the following step:
Enter the following command to associate a multicast group to an RP candidate:
CONFIGURATION
ip pim [vrf vrf-name] rp-Candidate interface [priority] [acl-name]
The specied acl-list is associated to the rp-candidate.
NOTE: You can create the ACL list of multicast prex using the ip access-list standard command.
