                   LISP Traffic Engineering Use-Cases
                       draft-farinacci-lisp-te-07

Abstract

   This document describes how LISP reencapsulating tunnels can be used
   for Traffic Engineering purposes.  The mechanisms described in this
   document require no LISP protocol changes but do introduce a new
   locator (RLOC) encoding.  The Traffic Engineering features provided
   by these LISP mechanisms can span intra-domain, inter-domain, or
   combination of both.

Status of This Memo
