Hi, all,

The rbridge architecture doc has been posted to the Internet drafts.
The only change was the reference to the P&AS doc, and that this document
is currently considered the product of a few authors rather than an
editor (that decision can be revised if accepted as a WG doc).

             The Architecture of an RBridge Solution to TRILL

Abstract

   RBridges are link layer (L2) devices that use routing protocols as a
   control plane. They combine the link layer ability to allow hosts to
   reattach without renumbering with network layer routing benefits.
   RBridges use existing link state routing to provide higher internal
   cross-section bandwidth, faster convergence under reconfiguration,
   and more robustness to link interruption than an equivalent set of
   conventional bridges using existing spanning tree forwarding. They
   are intended to apply to similar L2 network sizes as conventional
   bridges and are intended to be backward compatible with those bridges
   as both ingress/egress and transit. They also attempt to retain as
   much 'plug and play' as is already available in existing bridges.
   This document proposes the RBridge system as a solution to the TRILL
   problem. It also defines the RBridge architecture, presents its
   terminology, and describes its basic components and desired behavior.
   A separate document specifies the protocols and mechanisms that
   satisfy the architecture presented herein.
