Starting with Dell Networking OS 9.11.0.0, you can configure an RP candidate for aspecified range of multicast group address.The Configured multicast group ranges are used by the BSR protocol to advertise the candidate RPs in the bootstrap messages.You can configure the multicast group ranges as a standard ACL list of multicast prefixes. You can then associate the configured group listwith the RP candidate.NOTE: • If there is no multicast group list configured for the RP-candidate, the RP candidate will be advertised for all themulticast groups.To enable an RP to serve specific group of multicast addresses, perform the following step:Enter the following command to associate a multicast group to an RP candidate:CONFIGURATIONip pim [vrf vrf-name] rp-Candidate interface [priority] [acl-name]The specified acl-list is associated to the rp-candidate.NOTE: You can create the ACL list of multicast prefix using the ip access-list standardcommand.692 PIM Source-Specific Mode (PIM-SSM)
