Title : Analysis and Minimization of Microloops in Link-state Routing Protocols
Author(s) : A. Zinin
Filename : draft-ietf-rtgwg-microloop-analysis-01.txt
Pages : 17
Date : 2005-10-24
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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
