- Ou est le Root bridge ?
- Quest ce qui se passe en cas de faute ?
- Temps de convergence
- Beaucoup de lignes bloquées
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.
