                         draft-meyer-lisp-mn-11

Abstract

   This document describes how a lightweight version of LISP's ITR/ETR
   functionality can be used to provide seamless mobility to a mobile
   node.  The LISP Mobile Node design described in this document uses
   standard LISP functionality to provide scalable mobility for LISP
   mobile nodes.
