Layer 2 Virtual Private Network Extensions for Layer 2 Tunneling Protocol
RFC 4667, “Layer 2 Virtual Private Network Extensions for Layer 2 Tunneling Protocol”, is a Proposed Standard document published in September 2006 by W. Luo. The canonical text is published by the RFC Editor.
Abstract
The Layer 2 Tunneling Protocol (L2TP) provides a standard method for setting up and managing L2TP sessions to tunnel a variety of L2 protocols. One of the reference models supported by L2TP describes the use of an L2TP session to connect two Layer 2 circuits attached to a pair of peering L2TP Access Concentrators (LACs), which is a basic form of Layer 2 Virtual Private Network (L2VPN). This document defines the protocol extensions for L2TP to set up different types of L2VPNs in a unified fashion. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
