摘要： In a mesh network, when a wireless mesh link exists between a first mesh access point and a second mesh access point, the first mesh access point can deliver a multicast packet to the second mesh access point through the wireless mesh link. When the second mesh access point determines that the multicast packet from the first mesh access point is a redundant packet, the second mesh access point will send a multi-path notice to the first mesh access point. After receiving the multi-path notice, the first mesh access point stops delivering the multicast packet through the path.
