Because traffic patterns are not absolute. They are a prediction, but Murphy never cooperates and things sometimes vary from the expected prediction.

These mechanisms are not precluded. As we’ve stated, there are well-established techniques for redirecting the dark traffic. The comparable technique for IS-IS is to simply max-metric the link, which is in fact what we are doing. Regards, Tony
