   The IPv6 Virtual Private Network (VPN) Context Information Option
                   draft-bonica-6man-vpn-dest-opt-04

Abstract

   This document defines a new IPv6 Destination Option that can be used
   to encode Virtual Private Network (VPN) context information.  It is
   applicable when VPN payload is transported over IPv6.

1.  Introduction

   Virtual Private Network (VPN) technologies allow network providers to
   emulate private networks with shared infrastructure.  For example,
   assume that a red sites and blue sites connect to a provider network.
   The provider network facilitates communication among red sites and
   facilitates communication among blue sites.  However, it prevents
   communication between red sites and blue sites.

   The IETF has standardized many VPN technologies, including:

   o  Layer 2 VPN (L2VPN) [RFC6624].

   o  Layer 3 VPN (L3VPN) [RFC4364].

   o  Virtual Private LAN Service (VPLS) [RFC4761][RFC4762].

   o  Ethernet VPN (EVPN) [RFC7432].

   o  Pseudowires [RFC8077].

   The above-mentioned technologies include the following components:

   o  Customer Edge (CE) devices.

   o  Provider Edge (PE) devices.

   o  Routing Instances.

   o  VPN context information.

   o  Transport tunnels.

   CE devices participate in closed communities called VPNs.  CEs that
   participate in one VPN can communicate with one another but cannot
   communicate with CEs that participate in another VPN.
