Abstract

The IEEE 802.1 Provider Backbone Bridges (PBBs) specification defines anarchitecture and bridge protocols for interconnection of multiple ProviderBridged Networks (PBNs). Provider backbone bridging was defined by IEEE as aconnectionless technology based on multipoint VLAN tunnels. PBB can be usedto attain better scalability than Provider Bridges (PBs) in terms of thenumber of customer Media Access Control addresses and the number of serviceinstances that can be supported.

The Virtual Private LAN Service (VPLS) provides a framework for extendingEthernet LAN services, using MPLS tunneling capabilities, through a routedMPLS backbone without running the Rapid Spanning Tree Protocol (RSTP) orthe Multiple Spanning Tree Protocol (MSTP) across the backbone. As a result,VPLS has been deployed on a large scale in service provider networks.

This document discusses extensions to the VPLS Provider Edge (PE) modelrequired to incorporate desirable PBB components while maintaining theservice provider fit of the initial model.
