Proactive Network Verification and CI/CD Pipeline Integration
In this lab, you'll implement proactive network verification using pyATS and Batfish, then integrate automated testing into a CI/CD pipeline. You'll establish configuration baselines and build pre-flight checks that prevent misconfigurations from reaching production.

Challenge
Establish Operational Baselines and Detect Drift Using pyATS
To start, you will create a pyATS testbed file that defines connection parameters for cloud-based virtual routers, capture a comprehensive baseline of routing tables, and perform a diff to identify unintended VPC routing drift.
-
Challenge
Verify Network Configurations and Policies with Batfish
You will initialize a Batfish snapshot using exported cloud configurations and topology metadata, execute queries to verify security rules block unauthorized traffic, and analyze routing paths to ensure zone failure resilience.

Challenge
Implement a Pre-Flight CI Pipeline for Automated Testing
Finally, you will configure a CI runner triggered by Git push events, integrate a Python script that fails the build when Batfish detects a policy violation, and implement an automated rollback stage that restores the baseline state.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
