Abstract

   This document describes the use of the Locator/ID Separation Protocol
   (LISP) to create Virtual Private Networks (VPNs).  LISP is used to
   provide segmentation in both the LISP data plane and control plane.
   These VPNs can be created over the top of the Internet or over
   private transport networks, and can be implemented by Enterprises or
   Service Providers.  The goal of these VPNs is to leverage the
   characteristics of LISP - routing scalability, simply expressed
   Ingress site TE Policy, IP Address Family traversal, and mobility, in
   ways that provide value to network operators.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].
