A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : OSPF-lite
Author(s) : M. Thomas, et al.
Filename : draft-thomas-hunter-reed-ospf-lite-00.txt
Pages : 155
Date : 2007-8-31
This memo documents OSPF-lite. OSPF-lite is a link state routing
protocol, and a branch version of Internet Standard 54 OSPF [ref1].
It is designed to be run internal to a single Autonomous System.
Each OSPF-lite router maintains an identical database describing
the Autonomous System's topology. From this database, a routing table
is calculated by constructing a shortest-path tree.
OSPF-lite has been designed to provide a simpler version of the OSPF
protocol. A router running ospf-lite requires little configuration.
Areas are not implemented and all designated Router functionality has
been removed from the protocol. OSPF-lite will run over non fully
meshed clouds with no special OSPF configuration commands required.
Many of the Protocol complexities have been removed, and processor
overhead utilised in a different way. This work is intended to keep
pace with the vast increases in processor performance, memory size
and link capacity since OSPF was originally designed in 1989, with
the resulting benefits of simpler network design, configuration and
maintenance.
The differences between this memo and RFC 2328 are highlighted
throughout the document, but special attention should be placed on
Sections 2, 7, 16, and Appendix A; the latter describes detailed
packet structures. Many of the differences are backward compatible in
nature, but it is not envisioned that OSPF Version 2 will interoperate
with OSPF-lite, unless multiple instances are running and route
redistribution is employed.
The protocol has been designed with backward consistency in mind,
as far has been possible, to allow code modules developed for OSPF
Version 2 to be re-utilised.
This Internet Draft has been written within the same structure as
RFC 2328, to enable a section-by-section comparison with previous
versions of the main OSPF protocol. It is recommended that the
sections are directly compared. The authors? thanks in turn go the
developers of all of the features in RFC 2328, and associated RFCs,
and Standards.

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.
