Abstract

   This document specifies how to interconnect a pair of TRILL
   (Transparent Interconnection of Lots of Links) switch ports using
   pseudowires under existing TRILL and PWE3 (Pseudowire Emulation End-
   to-End) standards.

INTERNET-DRAFT                                      PWE3 TRILL Transport

1. Introduction

   The IETF has standardized the TRILL (Transparent Interconnection of
   Lots of Links) protocol [RFC6325] that provides optimal pair-wise
   data frame routing without configuration in multi-hop networks with
   arbitrary topology. TRILL supports multipathing of both unicast and
   multicast traffic. Devices that implement TRILL are called TRILL
   Switches or RBridges (Routing Bridges).

   Links between TRILL Switches can be based on arbitrary link
   protocols, for example PPP [RFC6361], as well as Ethernet [RFC6325].
   A set of connected TRILL Switches together form a TRILL campus which
   is bounded by end stations and layer 3 routers.

   This document specifies how to interconnect a pair of TRILL Switch
   ports using a pseudowire under existing TRILL and PWE3 (Pseudowire
   Emulation End-to-End) standards.
