   Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS
                  <draft-ietf-isis-rfc6326bis-03.txt>

Abstract

   The IETF TRILL (Transparent Interconnection of Lots of Links)
   protocol provides optimal pair-wise data frame forwarding without
   configuration in multi-hop networks with arbitrary topology and link
   technology, and 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.

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.
