 A New Internet-Draft is available from the on-line Internet-Drafts
 directories. This draft is a work item of the Point-to-Point Protocol
 Extensions Working Group of the IETF.


       Title     : Layer Two Tunneling Protocol "L2TP" - Security
		   Extensions for Non-IP networks
       Author(s) : Pat Calhoun, W. Mark Townsley
       Filename  : draft-ietf-pppext-l2tp-sec-00.txt
       Pages     : 8
       Date      : 06/16/1997

The L2TP Document defines the base protocol which describes the      method
of tunneling PPP data. The spec states that the security mechanism used
over an IP network is to use the IETF's IPSEC protocols.              L2TP
was designed in such a way as to be able to run over any underlying layer
(i.e. Frame Relay, ATM, etc.). This document specifies extensions to the
L2TP protocol in order to provide authentication and integrity of
individual packets in a tunneled session over a non-IP network. It does not
intend to provide a mechanism for encryption of packets.

NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.

implementation to automatically retrieve the ASCII version
