Title : MAC Hiding in an H-VPLS Environment
Author(s) : I. Cowburn
Filename : draft-cowburn-l2vpn-vpls-ldp-mac-hiding-00.txt
Pages : 12
Date : 2006-8-29
This document describes a mechanism for hiding customer MAC
addresses on a PE-rs in an H-VPLS environment. In the H-VPLS
hierarchy, a PE-rs is exposed to the MAC addresses for customers on
its directly attached MTU-s and the remote MAC addresses for all of
its configured VPLS instances. This can result in the requirement
to store a large number of a MAC addresses.
This document introduces the concept of an MTU-id per MTU-s which is
included with the customer frame sent by an MTU-s. The PE-rs is
then able to switch based on the MTU-id rather than the customer MAC
addresses, thereby reducing the address storage requirements on the
PE-rs to be of the order of the number of MTU-s.

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
