Title : ARP Mediation for IP interworking of Layer 2 VPN
Author(s) : H. Shah et al.
Filename : draft-shah-ppvpn-arp-mediation-02.txt

The VPWS service [L2VPN Framework] provides point-to-point
connections between pairs of Customer Edge (CE) devices. It does so
by binding two Attachment Circuits (each connecting a CE device with
a Provider Edge, PE, device) to a Pseudowire (connecting the two
PEs). In general, the Attachment Circuits must be of the same
technology (e.g., both ethernet, both ATM), and the Pseudowire must
carry the frames of that technology. However, if it is known that
the frames' payload consists solely of IP datagrams, it is possible
to provide a point-to-point connection in which the Pseudowire
connects Attachment Circuits of different technologies. This
requires the PEs to perform a function known as 'ARP Mediation'.
This document specifies the ARP Mediation function, and specifies
the encapsulation used to carry the IP datagrams on the Pseudowires
when ARP mediation is used.

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
