This document describes virtual private LAN service (VPLS) solution
over MPLS, called Generic VPLS/LPE (GVPLS) that emulates a partial
bridging functionality [802.1D] to connect customers LANs/VLANs
across the Metro and WAN Service Provider networks. This
functionality includes the MAC learning and forwarding to emulate
connectivity between the customer LANs/VLANs. This is a partial
bridging functionality since it is transparent to customer topology
and STP protocol.
For VPLS solutions, the VPLS Reference Model [VPLS-L2-FRW]
introduces two types of models: distributed and non-distributed.
While [LPE] framework, and [DTLS] solution present a distributed
model and [HVPLS] solution presents a non-distributed model, it is
recognized that both models may need to co-exist in the same in the
same SP network. This implies a need of a unified provisioning model
with signalling mechanisms to support these new classes of
solutions. The MAC learning process and the scalability in terms of
number of VPLSs and number of customer ports can be increased
significantly if some optimisations are provided in the Control and
Data plane.
The current draft presents the GVPLS solution that addresses such
issues. The term 'Generic' in this document is used to reflect the
unified aspect of the two models.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
