I-D ACTION:draft-ietf-l2tpext-failover-03.txt

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

	Title		: Fail Over extensions for L2TP 'failover'
	Author(s)	: R. Penno, K. Parikh
	Filename	: draft-ietf-l2tpext-failover-03.txt
	Pages		: 13
	Date		: 2004-3-11
	
L2TP is a connection-oriented protocol that has shared state between
active endpoints. Some of this shared state is vital for operation
but may be rather volatile in nature, such as packet sequence numbers
used on the L2TP Control Connection. When failure of one side of a
control connection occurs, a new control connection is created and
associated with the old connection by exchanging information about
the old connection. Such a mechanism is not intended as a replacement
for an active fail over with some mirrored connection states, but as
an aid just for those parameters that are particularly difficult to
have immediately available. Protocol extensions to L2TP defined in
this document are intended to facilitate state recovery, providing
additional resiliency in an L2TP network and improving a remote
system's layer 2 connectivity.

I-D ACTION:draft-ietf-l2tpext-pwe3-fr-03.txt

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

	Title		: Frame-Relay over L2TPv3
	Author(s)	: M. Townsley, et al.
	Filename	: draft-ietf-l2tpext-pwe3-fr-03.txt
	Pages		: 10
	Date		: 2004-3-26
	
The Layer 2 Tunneling Protocol, Version 3, (L2TPv3) defines a
   protocol for tunneling a variety of data link protocols over IP
   networks.  This document describes the specifics of how to tunnel
   Frame-Relay over L2TPv3, including frame encapsulation, virtual-
   circuit creation, deletion, and line status change notification.

I-D ACTION:draft-ietf-l2tpext-l2tp-base-12.txt

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

	Title		: Layer Two Tunneling Protocol (Version 3)
	Author(s)	: J. Lau, et al.
	Filename	: draft-ietf-l2tpext-l2tp-base-12.txt
	Pages		: 88
	Date		: 2004-3-26
	
This document describes 'version 3' of the Layer Two Tunneling
Protocol (L2TPv3). L2TPv3 defines the base control protocol and
encapsulation for tunneling multiple layer 2 connections between two
IP connected nodes. Additional documents detail the specifics for
each link-type being emulated.
