1.  Introduction

   The Transparent Interconnection of Lots of Links (TRILL) protocol
   [RFC6325] 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 Routing Bridges
   (RBridges).

   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 that
   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.
