Abstract

In many existing Virtual Private LAN Service (VPLS) deployments based on [RFC4762], pseudowire (PW) connectivity offers no Provider Edge (PE) node redundancy, or offers PE node redundancy with only 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. The redundancy mechanism will provide PE node redundancy and link redundancy in both domains. The PE throughout the document refers to a routing and bridging capable PE defined in [RFC4762], Section 10. The domain in this document refers to an autonomous system (AS), or other administrative domains.

            Redundancy Mechanism for Inter-domain VPLS Service

Abstract

   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    with only 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.
