Abstract
Router nodes of a wireless network deliver layer-3 multicast packets to subscribing end devices. In an embodiment, upon receiving a layer-3 multicast packet, a router determines a source that originated the layer-3 multicast packet. The router broadcasts at L2-level, the layer-3 multicast packet only if either one of a first condition and a second condition is satisfied. The first condition is satisfied only if (A) the source is not a descendant node of the router node according to the hierarchy, (B) the layer-3 multicast packet is received from a parent node, and (C) the layer-3 multicast address is subscribed to by a descendant of the router node. The second condition is satisfied only if (A) the source is a descendant of the router node, and (B) the layer-3 multicast packet is received from a child node according to the hierarchy, the source being reachable from the child node.
