New Draft L2VPN Extension for L2TP Spec by Cisco

It seems Cisco has submitted a new draft spec for L2VPN extension for L2TP… I’ll put this aside for future reading…

L2VPN Extensions for L2TP

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 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 L2VPN in a unified
fashion.
