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 failure. It is
normal, however, to observe short-term loops during the period of failure
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.
