BGP policy misconfigurations have caused a number of headline grabbing outages lately. While there are some common sense improvements operators can make to help mitigate some of the causes, that is not enough. There is a need for comprehensive validation of routing policy at the peering edge. This is where Batfish comes into the picture.

Batfish is an open-source network validation tool that builds models of routing and forwarding behavior of the network from the device configurations. Batfish enables operators to understand the impact of any configuration change before deploying it to the network.

This talk will cover how Batfish works and demonstrate how an operator can validate a proposed change to BGP routing policy.
