A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Routing Area Working Group Working Group of 
the IETF.

        Title           : Analysis and Minimization of Microloops in Link-state 
Routing Protocols

   Link-state routing protocols (e.g. OSPF or IS-IS) are known to
   converge to a loop-free state within a finite period of time after a
   change in the topology. It is normal, however, to observe short-term
   loops during the period of topology update propagation, route
   recalculation, and forwarding table update, due to the asynchronous
   nature of link-state protocol operation. This document provides an
   analysis of formation of such microloops and suggests simple
   mechanisms to minimize them.

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.
