A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IS-IS for IP Internets Working Group of the IETF.

        Title           : IS-IS Cryptographic Authentication
        Author(s)       : T. Li, R. Atkinson
        Filename        : draft-ietf-isis-hmac-03.txt

This document describes the authentication of IS-IS PDUs using the
HMAC-MD5 algorithm [1].  IS-IS is specified in [2],  with  extensions
to support IPv4 described in [3].  The base specification includes an
authentication mechanism  that  allows  for  multiple  authentication
algorithms.   The base specification only specifies the algorithm for
cleartext passwords.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
                
                
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
