             Redundancy provisioning for VPLS Inter-domain
            draft-ietf-l2vpn-vpls-inter-domain-redundancy-05

Abstract

   In many existing Virtual Private LAN Service (VPLS) deployments based
   on RFC 4762, inter-domain connectivity has been deployed without node
   redundancy, or with node redundancy in a single domain.  This
   document describes a solution for inter-domain VPLS based on RFC 4762
   with node and link redundancy in both domains.

Internet-Draft      Redundancy for VPLS Inter-domain          April 2014

1.  Introduction

   In many existing Virtual Private LAN Service (VPLS) deployments based
   on [RFC4762], inter-domain connectivity has been deployed without
   node redundancy, or with node redundancy in a single domain.  This
   document is to provide a service protection mechanism for inter-
   domain VPLS based on [RFC4762].  The protection mechanism will
   provide edge node redundancy and link redundancy in both domains.
   The domain in this document refers to autonomous system (AS), or
   other administrative domains.

   The solution relies on the use of ICCP [I-D.ietf-pwe3-iccp] to
