Title : Virtual Private LAN Services over MPLS
Author(s) : M. Lasserre et al.
Filename : draft-ietf-ppvpn-vpls-ldp-00.txt
Pages : 25
Date : 2003-6-24
This document describes a virtual private LAN service (VPLS)
solution over MPLS, also known as Transparent LAN Services (TLS). A
VPLS creates an emulated LAN segment for a given set of users. It
delivers a layer 2 broadcast domain that is fully capable of
learning and forwarding on Ethernet MAC addresses that is closed to
a given set of users. Many VPLS services can be supported from a
single PE node.
This document describes the control plane functions of signaling
demultiplexor labels, extending [PWE3-CTRL] and rudimentary support
for availability (multi-homing). It is agnostic to discovery
protocols. The data plane functions of forwarding are also
described, focusing, in particular, on the learning of MAC
addresses. The encapsulation of VPLS packets is described by [PWE3-
ETHERNET].

NOTE: The mail server at ietf.org 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
