A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Open Shortest Path First IGP Working Group of the IETF.

        Title : OSPF Refresh and Flooding Reduction in Stable
                          Topologies
        Author(s) : P. Pillay-Esnault
        Filename : draft-pillay-esnault-ospf-flooding-05.txt
        Pages : 4
        Date : 2003-3-28

This document describes an extension to the OSPF protocol to
eliminate or reduce periodic flooding of Link State Advertisements
in stable topologies.
The current behavior of OSPF requires that all LSAs be refreshed
every 30 minutes regardless of the stability of the network except
for DoNotAge LSAs. This document proposes to generalize the use of
DoNotAge LSAs to reduce protocol traffic in stable topologies.

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.
