A carrier-class router must be able to forward traffic
at wire speed, while managing topology changes to routes
not currently in use. Determining the routing stability
of a core Internet router involves measuring the impact
of the routing updates on the forwarding performance
of the router.
This concise application note explains what is meant
by routing instability and what needs to be tested on
the router to determine the router's performance capabilities
and limitations amidst topology.
