Title : ARP Mediation for IP Interworking of Layer 2 VPN
Author(s) : H. Shah, et al.
Filename : draft-ietf-l2vpn-arp-mediation-08.txt
Pages : 25

The VPWS service [L2VPN-FRM] 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". ARP Mediation refers to the
process of resolving Layer 2 addresses when different resolution
protocols are used on either Attachment Circuit. The methods
described in this document are applicable even when the CEs run
a routing protocol between them, as long as the routing protocol
runs over IP.

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
