          RSVP-TE Extensions for Associated Bidirectional LSPs
         draft-ietf-ccamp-mpls-tp-rsvpte-ext-associated-lsp-10

Abstract

   This document describes Resource reSerVation Protocol (RSVP)
   extensions to bind two point-to-point unidirectional Label Switched
   Paths (LSPs) into an associated bidirectional LSP.  The association
   is achieved by defining new Association Types for use in ASSOCIATION
   and in Extended ASSOCIATION Objects.  One of these types enables
   independent provisioning of the associated bidirectional LSPs on both
   sides, while the other enables single sided provisioning.  The
   REVERSE_LSP Object is also defined to enable a single endpoint to
   specify all the parameters of an associated LSP in the single sided
   provisioning case.
