I read a lot of issues with simulated router in real SP lab : process down, link down, neighbor doesn't want to come up even all config are correct, and crazy behaviour where you could spend a lot of time scratching your head and bang your head to wall, before finally ask Proctor. Proctor sometimes also struggle to fix it.
My question:
a. What is the most common issue come out and how to detect it ?
b. Can we reload simulated routers and get it recovered by ourselves ?
