Claim 0:
1. A computer-implemented method for broadcasting a bootstrap message (BSM) in a multicast network, the method comprising:
receiving, at an elected bootstrap router (E-BSR) in the multicast network, one or more advertisement messages from one or more candidate Rendezvous Points (C-RPs) to update an RP set for the multicast network;
comparing, at the E-BSR, each received advertisement message to a previous advertisement message received in a last advertisement interval from a same C-RP;
verifying, at the E-BSR, whether any difference exists for each advertisement message;
in response to no difference identified for the one or more advertisement messages, the E-BSR incorporates in a BSM header of the BSM a first flag with a value indicating no difference for the RP set and broadcasts the BSM, which comprises the BSM header and no group sections for the RP set, to multicast routers coupled to the E-BSR in the multicast network; and
in response to difference identified for one or more received advertisement messages, the E-BSR updates the RP set using the one or more received advertisement messages, incorporates in the BSM header of the BSM the first flag with a value indicating change occurred in the RP set, and broadcasts the BSM with at least changed part of the RP set to multicast routers coupled to the E-BSR in the multicast network.
