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]
