priorities of multiple routers are similar, the IP addresses should
be compared. The candidate-BSR with greater address will
become the formal BSR.
5. To Configure candidate-RPs, use
rp-candidate <interface-
name> [group-list <access-list-number>] [priority
<priority>] command in pimsm configuration mode, as
shown in Table 390.

In the PIM-SM, the RP is a root of the shared multicast tree.
It is responsible for sending multicast packets to the
receiving member of the group in the downstream along the
shared tree. Each multicast group has only one formal RP.
The default priority of the candidate-RP is 0. The candidate-
RP with greater priority value has greater priority.

Setting PIM-SM Global Parameters
When PIM-SM is running, different parameters have different
default value. These parameters can be set to optimize networks.
This topic describes how to set PIM-SM global parameters
