         Extensions to RSVP-TE for LSP Egress Local Protection
             draft-ietf-teas-rsvp-egress-protection-03.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), which is a
   Point-to-Point (P2P) LSP or a Point-to-Multipoint (P2MP) LSP.
