Abstract
This document provides requirements for Layer 2 Provider-Provisioned
Virtual Private Networks (L2VPNs). It first provides taxonomy and
terminology and states generic and general service requirements. It
covers point-to-point VPNs, referred to as Virtual Private Wire
Service (VPWS), as well as multipoint-to-multipoint VPNs, also known
as Virtual Private LAN Service (VPLS). Detailed requirements are
expressed from both a customer as well as a service provider
perspectives.
