The IESG has received a request from the Layer 2 Virtual Private Networks
WG (l2vpn) to consider the following document:
- 'ARP Mediation for IP Interworking of Layer 2 VPN'
<draft-ietf-l2vpn-arp-mediation-17.txt> as a Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2011-09-12. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.
Abstract
The Virtual Private Wire Service (VPWS) [RFC4664] 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.
