    the multicast group identification can be used to identify a multicast group of hosts to which the packet is being sent;

    comparing the bit mask with forwarding information stored by the node;

    selecting at least one neighbor node based on the comparing;

    forwarding the packet to the at least one neighbor node;

    receiving a first advertisement at the node, wherein the node receives the first advertisement from a first edge node of the network, and wherein the first advertisement comprises first information identifying a first bit position in the bit mask and the first edge node;

    receiving a second advertisement at the node, wherein the node receives the second advertisement from a second edge node of the network, and wherein the second advertisement comprises second information identifying a second bit position in the bit mask and the second edge node;

    generating the forwarding information at the node, wherein the forwarding information is generated based on the first information and the second information, and;
