The IESG has approved the following document:
- 'Redundancy Mechanism for Inter-domain VPLS Service'
  (draft-ietf-l2vpn-vpls-inter-domain-redundancy-07.txt) as Proposed
Standard

This document is the product of the Layer 2 Virtual Private Networks
Working Group.

The IESG contact persons are Adrian Farrel and Alia Atlas.

Technical Summary:

   In many existing Virtual Private LAN Service (VPLS) inter-domain
   deployments (based on RFC 4762), pseudowire (PW) connectivity offers
   no Provider Edge (PE) node redundancy, or offers PE node redundancy
   only with a single domain.  This deployment approach incurs a high
   risk of service interruption, since at least one domain will not
   offer PE node redundancy.  This document describes an inter-domain
   VPLS solution that provides PE node redundancy across domains.

Working Group Summary:

   This document is an L2VPN Working Group document, and has been discussed in 
   the working group through multiple iterations of the draft and its predecessor draft 
   (draft-liu-l2vpn-vpls-inter-domain-redundancy).  It has been essentially stable since 
   WG adoption in May 2013.  Prior to WG adoption the protocol operations in the 
   predecessor draft were removed, leaving the draft as a simple BCP on options for 
   configuring redundancy for inter-domain VPLS services.

Document Quality:

     The document is short (11 pages in total) and to the point.
