Virtual Private LAN Service (VPLS) Interoperability
with Customer Edge (CE) Bridges
Abstract
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.
