The IPv6 Virtual Private Network (VPN) Context Information Option
draft-bonica-6man-vpn-dest-opt-05
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.
