The ability to determine paths of point-to-multipoint (P2MP) Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering Label Switched Paths (TE LSPs) is one the key requirements for Path Computation Element (PCE). The RFC 6006 and RFC 7334 describes these mechanisms for intra and inter domain path computation via PCE(s). This document describes the motivation and PCEP extension for explicitly specifying abstract nodes for inclusion or exclusion for a subset of destinations during P2MP path computation via PCE(s).
