         Extensions to RSVP-TE for LSP Egress Local Protection
             draft-ietf-teas-rsvp-egress-protection-00.txt

Abstract

   This document describes extensions to Resource Reservation Protocol -
   Traffic Engineering (RSVP-TE) for locally protecting egress nodes of
   a Traffic Engineered (TE) Label Switched Path (LSP) in a Multi-
   Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) network.
