Abstract
A method is provided in one example embodiment and includes establishing at least one fixed topology distribution tree in a network, where the fixed topology distribution tree comprises one root node and a plurality of leaf nodes connected to the root node; maintaining at the root node an indication of multicast group interests advertised by the leaf nodes; and pruning traffic at the root node based on the advertised multicast group interests of the leaf nodes. In one embodiment, the root node is a spine switch and each of the leaf nodes is a leaf switch and each of the leaf nodes is connected to the root node by a single hop.
