The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. [I-D.ietf-pce-association-group] proposed an association mechanism for a set of LSPs. This document proposes a set of extensions to PCEP to associate a grouping of multi-layer LSPs. The extensions define a mechanism to create associations between upper-layer LSP and related lower-layer LSPs.
