Electing an RP using the BSR Mechanism
Every PIM router within a domain must map a particular multicast group address to the same RP. The group-to-RP mapping may be
statically or dynamically congured. RFC 5059 species a dynamic, self-conguring method called the Bootstrap Router (BSR) mechanism,
by which an RP is elected from a pool of RP candidates (C-RPs).
