                 TRILL Transparent Transport over MPLS 
               <draft-ietf-trill-transport-over-mpls-02>

Abstract

   This document specifies how to interconnect multiple Transparent
   Interconnection of Lots of links (TRILL) sites with an intervening
   MPLS network using existing TRILL and VPLS standards. This draft
   addresses two problems as follows:

   1) Providing connection between more than two TRILL sites that 
   are separated by MPLS provider network.

   2) Providing a single logical virtualized TRILL network for 
   different tenants that are separated by an MPLS provider network. 

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF), its areas, and its working groups.  Note that
   other groups may also distribute working documents as
   Internet-Drafts.
