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.
