Consequently, the network could be one link failure away from an outage that leads to a massive loss of revenue and reputation.\n", "\n", "Fortunately, based just on device configurations, Batfish makes it easy to *proactively* analyze the network behavior under failures and offer guarantees on its tolerance to a range of failure scenarios. \n", "\n", "In this notebook, we will show how to use Batfish to analyze network behavior under failures.
