A method and system for updating a multicast state of a multicast group at a first mesh access point as provided improves network efficiency. According to one aspect, the method includes processing a multicast member join request for the multicast group received from a first wireless node. A proxy update message for the first wireless node received from a third mesh access point is then processed. The first wireless node connects to a second mesh access point after joining the multicast group via the first mesh access point, and the third mesh access point is a root node of a mesh tree of which the second mesh access point is a node. An Internet Group Management Protocol (IGMP) query message for the multicast group is then generated. A multicast update (MUPD) packet is then transmitted to an upstream node, whereby a multicast state is updated at the upstream node.
