BSR
PIM SM uses a Bootstrap Router (BSR), which advertises information to other multicast routers
about the rendezvous point (RP). In a given network, a set of routers can be administratively
enabled as candidate bootstrap routers(C-BSR). If it is not apparent which router should be the
BSR, the candidates flood the domain with advertisements. The router with the highest priority
is elected. If all the priorities are equal, then the candidate with the highest IP address becomes
the BSR.
