Figure 526: Configuring Global Settings for PIM-SM

Use the Routing Protocol > PIM > SM (BSR Candidate) page to configure the switch
as a Bootstrap Router (BSR) candidate.
Command Usage
◆
When this router is configured as a BSR candidate, it starts sending bootstrap
messages to all of its PIM-SM neighbors. The primary IP address of the
designated VLAN is sent as the candidate's BSR address. Each neighbor
receiving the bootstrap message compares the BSR address with the address
from previous messages. If the current address is the same or a higher address,
it accepts the bootstrap message and forwards it. Otherwise, it drops the
message.
◆
This router will continue to be the BSR until it receives a bootstrap message
from another candidate with a higher priority (or a higher IP address if the
priorities are the same).
◆
To improve failover recovery, it is advisable to select at least two core routers in
diverse locations, each to serve as both a candidate BSR and candidate RP. It is
also preferable to set up one of these routers as both the primary BSR and RP.
