Abstract

   The IETF has standardized TRILL (TRansparent Interconnection of Lots
   of Links), a protocol for least cost transparent frame routing in
   multi-hop networks with arbitrary topologies and link technologies,
   using link-state routing and encapsulation with a hop count.

   The TRILL base protocol standard supports labeling of TRILL data with
   up to 4K IDs. However, there are applications that require more fine-
   grained labeling of data. This document updates RFC 6325 by
   specifying extensions to the TRILL base protocol to accomplish this.

Status of This Memo

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

   Distribution of this document is unlimited. Comments should be sent
   to the TRILL working group mailing list.

   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.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference

1. Introduction

   The IETF has standardized the TRILL (TRansparent Interconnection of
   Lots of Links) protocol [RFC6325]. TRILL switches provide a solution
   for least cost transparent frame routing in multi-hop networks with
   arbitrary topologies and link technologies, using [IS-IS] [RFC6165]
