Abstract
A method is provided for pruning an MP2MP tree. The method includes, in a first node of an MP2MP LSP tree, determining whether the first node has only a single replication branch for the MP2MP LSP tree, the single replication branch representing a downstream path to only a second node of the plurality of nodes. In response to determining that the first node has only a single replication branch for the MP2MP LSP tree, sending a message to the second node indicating that the second node should refrain from sending upstream traffic towards the first node, and in response to determining that the first node does not have only a single replication branch for the MP2MP LSP tree, refraining from sending a message to the second node indicating that the second node should refrain from sending upstream traffic of the MP2MP LSP tree towards the first node.
