Abstract
In one embodiment, a method provides for hosting, by a first virtual switch of an overlay virtual network, a multi-destination receiver for a multi-destination group. The first virtual switch receives, from a second virtual switch hosting a multi-destination sender for the multi-destination group, a single copy of a multi-destination packet, wherein the first virtual switch is represented by a node of a plurality of nodes in a tree created by a network controller, and wherein each of the nodes represents a virtual switch that has registered a multi-destination receiver with the network controller. The first virtual switch forwards the received multi-destination packet to a third virtual switch hosting a multi-destination receiver for the multi-destination group, wherein the third virtual switch is represented in the tree by a child of the node.
