II. Configure BSRs
The BSR is the management core in a PIM-SM network. Candidate-RPs send
announcement to the BSR, which is responsible for collecting and advertising the
information about all candidate-RPs.
It should be noted that there can be only one BSR in a network but you can configure
multiple candidate-BSRs. In this case, once a BSR fails, you can switch over to another
BSR. A BSR is elected among the C-BSRs automatically. The C-BSR with the highest
priority is elected as the BSR. If the priority is the same, the C-BSR with the largest IP
address is elected as the BSR.
III. Configure static RP
RP is the kernel router for the multicast routing. If the dynamic RP elected by BSR
mechanism fails, a static RP can be configured. As the backup of dynamic RP, static RP
improves robustness and operability of the multicast network.
