PIM Group-to-RP Mappings
Use the show ip pim sparse-mode rp mapping command to display the group-
to-RP mapping details. The output displays information about RP candidates.
There are two RP candidates for the group range 224.0.0.0/4. RP Candidate
10.10.1.5 has a default priority of 192, whereas, RP Candidate
172.16.1.2 has been configured to have a priority of 2. Since RP candidate
172.16.1.2 has a higher priority, it is selected as RP for the multicast group
224.0.0.0/ 4.

RP Details
To display information about the RP router for a particular group, use the
following command. This output displays that 172.16.1.2 has been chosen as
the RP for the multicast group 224.0.1.3.

After RP information reaches all PIM routers in the domain, various state
machines maintain all routing states as the result of Join/Prune from group
membership.
