OpenSM does not overlay multiple groups (MGIDs) with the same
characteristics on the same MLID. It uses unique MLIDs per group.

MLIDs start at 0xC000 and are constrained by the least capable switch
(in terms of SwitchInfo::MulticastFDBCap).

Are you just asking or are you having some issue in this area ?
