Title : OSPF Database Exchange Summary List Optimization
Author(s) : R. Ogier
Filename : draft-ietf-ospf-dbex-opt-02.txt
Pages : 6
Date : 2007-12-11
This document describes a backward compatible optimization for the
Database Exchange process in OSPFv2 and OSPFv3. In this
optimization, a router does not list an LSA in Database Description
packets sent to a neighbor, if the same or a more recent instance of
the LSA was listed in a Database Description packet already received
from the neighbor. This optimization reduces Database Description
overhead by about 50% in large networks. This optimization does not
affect synchronization, since it only omits unnecessary information
from Database Description packets.

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.
