Title : IP-Only LAN Service (IPLS)
Author(s) : H. Shah, et al.
Filename : draft-ietf-l2vpn-ipls-07.txt
Pages : 22
Date : 2007-7-8
A Virtual Private LAN Service (VPLS) [VPLS] is used to interconnect
systems across a wide-area or metropolitan-area network, making it
appear that they are on a private LAN. The systems which are
interconnected may themselves be LAN switches. If, however, they
are IP hosts or IP routers, certain simplifications to the operation
of the VPLS are possible. We call this simplified type of VPLS an
"IP-only LAN Service" (IPLS). In an IPLS, as in a VPLS, LAN
interfaces are run in promiscuous mode, and frames are forwarded
based on their destination MAC addresses. However, the maintenance
of the MAC forwarding tables is done via signaling, rather than via
the MAC address learning procedures specified in [IEEE 802.1D].
This draft specifies the protocol extensions and procedures for
support of the IPLS service.

In the body type:
"FILE /internet-drafts/draft-ietf-l2vpn-ipls-07.txt".
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.
