Configure BSR
BSR is the management center of PIMSM network. It is in charge of collecting messages sent
by candidate RPs and broadcast them.
Only one BSR can exist within a network, but more than one C-BSR (Candidate-BSR) can be
configured. In this way, if some BSR goes wrong, it can switch to another. C-BSRs elect BSR
automatically.
