Command Usage
• When the
ip pim bsr-candidate
command is entered, the router
starts sending bootstrap messages to all of its PIM-SM neighbors. The
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.
