Abstract
A method of routing traffic for multi-cast routing through a node of a network that utilizes loop-free alternative paths is presented. The method includes receiving a join in the node from a second node in the network on a shortest path between the node and the second node; retrieving loop-free alternative paths to the second node; and adding an entry to a multi-cast routing table at the node that is based on a group that includes the shortest path to the second node and the loop-free alternative paths to the second node as cost equivalent paths.
