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           : Basic Specification for IP Fast-Reroute: Loop-free 
Alternates
        Author(s)       : A. Atlas, A. Zinin
        Filename        : draft-ietf-rtgwg-ipfrr-spec-base-09.txt
        Pages           : 30
        Date            : 2007-9-21
        
This document describes the use of loop-free alternates to provide
   local protection for unicast traffic in pure IP and MPLS/LDP networks
   in the event of a single failure, whether link, node or shared risk
   link group (SRLG).  The goal of this technology is to reduce the
   micro-looping and packet loss that happens while routers converge
   after a topology change due to a failure.  Rapid failure repair is
   achieved through use of precalculated backup next-hops that are loop-   free 
and safe to use until the distributed network convergence
   process completes.

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.
