This book focuses on Apstra, Juniper’s intent-based data center networking solution. Apstra takes high-level user objectives (intent) and coverts them into Juniper validated, best practice designs. Device configurations are automatically rendered from the design with no user input required. Once deployed, Apstra leverages closed-loop automation and assurance to provide a complete fabric management solution.The authors provide a step-by-step design, deploy, and maintenance guide to Apstra.
