Abstract
The Layer Two Tunneling Protocol (L2TP) provides a standard method
for transporting the link layer of the Point-to-Point Protocol (PPP)
between a dial-up server and a Network Access Server, using a network
connection in lieu of a physical point-to-point connection. This
document describes the use of an Asynchronous Transfer Mode (ATM)
network for the underlying network connection. ATM User-Network
Interface (UNI) Signaling Specification Version 4.0 or Version 3.1
with ATM Adaptation Layer 5 (AAL5) are supported as interfaces to the
ATM network.
Applicability
This specification is intended for implementations of L2TP that use
ATM to provide the communications link between the L2TP Access
Concentrator and the L2TP Network Server.
