Abstract:
Disclosed is a mechanism that provides the extensions of PCEP message and the objects to support PCECC with P2MP capability in downloading the labels for branch node of P2MP TE LSPs. In one implementation, various embodiments provide an apparatus, a system, a node and a method that receives a PCLabelUpd message with all the extensions and the objects to support PCECC with P2MP capability, detects the object and identifies that the label download is for P2MP TE LSP and for this LSP. In those embodiments, the apparatus/the system/the node acts as a branch node, and thereby the apparatus/the system/the node downloads all the labels specified in the object to data plane with respect to any existing branch node download mechanism for a P2MP TE LSP.
