METHOD AND APPARATUS FOR SPANNING TREES FOR COMPUTED SPRING MULTICAST

摘要

A method is implemented by a network device to compute a multicast distribution tree (MDT) that is a spanning tree in a source packet in routing (SPRING) network for a multicast group, where a first forwarding element has advertised itself as the root of the multicast group and at least one forwarding element has advertised a send and/or receive interest in the multicast group. The result of the spanning tree computation is utilized to update the forwarding information base (FIB) of the network device.
