Support for Resource Reservation Protocol Traffic Engineering (RSVP-TE)
              in Layer 3 Virtual Private Networks (L3VPNs)

Abstract

   IP Virtual Private Networks (VPNs) provide connectivity between sites
   across an IP/MPLS backbone.  These VPNs can be operated using
   BGP/MPLS, and a single Provider Edge (PE) node may provide access to
   multiple customer sites belonging to different VPNs.

   The VPNs may support a number of customer services, including RSVP
   and Resource Reservation Protocol Traffic Engineering (RSVP-TE)
   traffic.  This document describes how to support RSVP-TE between
   customer sites when a single PE supports multiple VPNs and labels are
   not used to identify VPNs between PEs.
