    abstract =  {This document describes the necessary requirements to allow a service provider to extend the reach of pseudowires across multiple domains. These domains can be autonomous systems under one provider administrative control, IGP areas in one autonomous system, different autonomous systems under the administrative control of two or more service providers, or administratively established pseudowire domains.
