• When multiple BSR RP-candidates advertise the same group list (for example, 224.0.0.0/4) and are
configured with the same BSR RP-candidate priority, the system elects the BSR RP-candidate with the
highest IP address as the RP for any multicast address specified in its group list (see configuration example
3).
