Abstract
One embodiment of the present invention sets forth a technique for establishing communications within a multicast group of nodes included in a mesh network. The technique includes receiving a first unicast message that includes a multicast join request from a member node included in the multicast group, wherein the multicast join request specifies a first shortest path from the member node to a multicast group leader also included in the multicast group. The technique also includes forwarding the first unicast message to the multicast group leader along the first shortest path, and forwarding a second unicast message from the multicast group leader to the member node along a second shortest path, wherein the second unicast message includes a multicast join acknowledgment. The technique further includes declaring a first node as a multicast forwarder in the multicast group, wherein the first node is responsible for forwarding the second unicast message.
