Enabling RP to Server Specific Multicast Groups
When you configure an RP candidate, its advertisement is sent to the entire multicast address range and the group-to-RP
mapping is advertised for the entire range of multicast address. Starting with Dell Networking OS 9.11.0.0, you can configure an
RP candidate for a specified 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 list with the RP candidate.
NOTE: • If there is no multicast group list configured for the RP-candidate, the RP candidate will be advertised for all the
multicast 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:
CONFIGURATION
ip 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 standard command.
