La résilience est le problème du fabriquant

Aucun routeur n’est résilient aux fautes logicielles
Vous avez toujours besoin d’un plus gros routeur
Notes:
Calculate who is root bridge. You have 3 hours. Go.
Things to emphasize: Lots of redundancy here – lots of redundant links. Some lack of consistency. Yet still a terrible design.
This makes our key point: Resiliency is more than just adding redundant links. As a matter of fact, having lots of redundant links can actually hurt you, because it makes spanning tree and Dijkstra calculations more difficult – thus hurting your convergence time.
