LISP Virtual Private Networks (VPNs)
draft-ietf-lisp-vpn-06
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].
