One of the main motivations behind Virtual Private LAN Service (VPLS) is 
its ability to provide connectivity not only among customer routers and
servers/hosts but also among customer IEEE bridges.  VPLS is expected to
deliver the same level of service that current enterprise users are 
accustomed to from their own enterprise bridged networks or their 
Ethernet Service Providers.

When customer edge (CE) devices are IEEE bridges, then there are certain
issues and challenges that need to be accounted for in a VPLS network.  The
majority of these issues have been addressed in the IEEE 802.1ad
standard for provider bridges and they can be leveraged for VPLS
networks.  This document extends the provider edge (PE) model described in
RFC 4664 based on IEEE 802.1ad bridge module, and it illustrates a clear
demarcation between the IEEE bridge module and IETF LAN emulation
module.  By doing so, it shows that the majority of interoperability
issues with CE bridges can be delegated to the 802.1ad bridge
module, thus removing the burden on the IETF LAN emulation module
within a VPLS PE.  This document is not an Internet Standards Track 
specification; it is published for informational purposes.

This document is a product of the Layer 2 Virtual Private Networks Working Group of the IETF.
