    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.},
