Batfish Bootcamp

Batfish is an open-source network analysis tool that models your network so that you can validate your network changes before pushing them into your live network. With Batfish, you can validate configuration, simulate network failure, test ACL behaviour and a TON more!

By the end of this bootcamp, you will be able to automate the validation and analysis of your network in terms of configuration, routing, forwarding and ACL behaviour through both Python-based scripts and CI integration.


In this bootcamp, you will learn,
