   Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS

Abstract

   The IETF Transparent Interconnection of Lots of Links (TRILL)
   protocol provides optimal pair-wise data frame forwarding without
   configuration in multi-hop networks with arbitrary topology and link
   technology; it also provides support for multipathing of both unicast
   and multicast traffic.  This document specifies the data formats and
   code points for the IS-IS extensions to support TRILL.  These data
   formats and code points may also be used by technologies other than
   TRILL.  This document obsoletes RFC 6326.
