摘要：
In one embodiment, a trigger to add a leaf node to a multicast group of a computer network is detected, and the leaf node may determine a root node of the multicast group to request a path between a tunnel tree and the leaf node of the multicast group. In response to the multicast group having an existing tree, a reply is received from the root node with a computed path to add the leaf node to the tree at a selected node of the tree. The leaf node may then be added to the multicast group tunnel tree over the computed path at the selected node.
