             LISP Network Element Deployment Considerations
                   draft-ietf-lisp-deployment-12.txt

Abstract

   This document is a snapshot of different Locator/Identifier
   Separation Protocol (LISP) deployment scenarios.  It discusses the
   placement of new network elements introduced by the protocol,
   representing the thinking of the LISP working group as of Summer
   2013.  LISP deployment scenarios may have evolved since.  This memo
   represents one stable point in that evolution of understanding.
