This document describes a Virtual Private LAN Service
(VPLS)
solution using pseudowires, a service previously implemented
over
other tunneling technologies and known as Transparent LAN
Services
(TLS). A VPLS creates an emulated LAN segment for a given
set of
users; i.e., it creates a Layer 2 broadcast domain that is
fully
capable of learning and forwarding on Ethernet MAC addresses
and that
is closed to a given set of users. Multiple VPLS services
can be
supported from a single Provider Edge (PE) node.
This document describes the control plane functions of
signaling
pseudowire labels using Label Distribution Protocol (LDP),
extending RFC 4447. 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 RFC 4448. [STANDARDS TRACK]
This document is a product of the Layer 2 Virtual Private
Networks
Working Group of the IETF.
This is now a Proposed Standard Protocol.
STANDARDS TRACK: This document specifies an Internet
standards track
protocol for the Internet community,and requests discussion
and
suggestions for improvements.Please refer to the current
edition of the
