Abstract
Layer Two Tunneling Protocol (L2TP) describes a mechanism to tunnel
Point-to-Point (PPP) sessions. The protocol has been designed to be
independent of the media it runs over. The base specification
describes how it should be implemented to run over the User Datagram
Protocol (UDP) and the Internet Protocol (IP). This document
describes how L2TP is implemented over Frame Relay Permanent Virtual
Circuits (PVCs) and Switched Virtual Circuits (SVCs).
Applicability
This specification is intended for those implementations which desire
to use facilities which are defined for L2TP and applies only to the
use of Frame Relay pont-to-point circuits.
1.0 Introduction
L2TP [1] defines a general purpose mechanism for tunneling PPP over
various media. By design, it insulates L2TP operation from the
details of the media over which it operates. The base protocol
specification illustrates how L2TP may be used in IP environments.
This document specifies the encapsulation of L2TP over native Frame
Relay and addresses relevant issues.
