  PCEP Extensions for Establishing Relationships Between Sets of LSPs
                  draft-ietf-pce-association-group-02

Abstract

   This document introduces a generic mechanism to create a grouping of
   LSPs in the context of a PCE.  This grouping can then be used to
   define associations between sets of LSPs or between a set of LSPs and
   a set of attributes (such as configuration parameters or behaviors),
   and is equally applicable to the active and passive modes of a
   stateful PCE as well as a stateless PCE.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].
