The IP multicast group address that, when combined with the corresponding value of pimBsrCandidateRPGroupPrefixLength, identifies a group prefix for which the local router will advertise itself as a Candidate-RP. The InetAddressType is given by the pimBsrCandidateRPAddressType object. This address object is only significant up to pimBsrCandidateRPGroupPrefixLength bits. The remainder of the address bits are zero. This is especially important for this field, which is part of the index of this entry. Any non-zero bits would signify an entirely different entry.
