The Path Computation Element (PCE) has been recognized as an appropriate technology for the determination of inter-domain paths of P2MP TE LSPs. This document describes the procedures and extensions to the PCE communication Protocol (PCEP) to handle requests and responses for the computation of inter-domain paths for P2MP TE LSPs.}, }
