Design, Operate, and Scale Advanced EVPN VXLAN Fabrics
Modern data centers are transforming rapidly--driven by AI workloads, cloud-native applications, and increasingly diverse multi-vendor environments. Mastering Advanced Juniper Data Centers is the hands‑on guide for experienced network professionals who need to design, deploy, and scale EVPN VXLAN fabrics built for today's most demanding infrastructures.
This book goes beyond theory. Through clear explanations, packet‑level walkthroughs, and real-world architectural insights, you'll learn how next‑generation data centers actually work in production. You'll explore advanced topics including multi-tenant data center fabrics and service-chaining, multicast, multi‑vendor EVPN interoperability, Day‑2 operations with Juniper Apstra, and network infrastructure observability with streaming telemetry using gNMI.
Standout features of this book are its dedicated focus on EVPN interoperability across Cisco, Arista and Juniper network operating systems and advanced multicast designs--topics rarely addressed in traditional networking literature. Whether you're building new infrastructure or optimizing complex fabrics, you'll gain the expertise to deliver scalable, resilient, data center networks.
What You'll Learn:
- Design and deploy multi-tenant EVPN VXLAN fabrics with service-chaining
- Implement multicast in modern EVPN VXLAN networks
- Understand packet flows through hands‑on captures and walkthroughs
- Build and troubleshoot multi‑vendor EVPN fabrics (Juniper, Cisco, Arista)
- Perform Day‑2 operations with Juniper Apstra
- Deploy modern data center fabrics using Terraform for Juniper Apstra
- Build and deploy an observability stack for streaming telemetry using gNMI
Who This Book Is For:
- Data center network architects
- Senior network and NetOps engineers
- Professionals designing, deploying and implementing modern data centers, working with EVPN VXLAN, Junos OS, or Juniper Apstra

About the Author :
Aninda Chatterjee holds a Bachelor of Engineering degree in Information Science. His networking career started at AT&T, troubleshooting Layer 1 circuit issues (T1/DS3 circuits--anyone remember those?), eventually transitioning to customer support at Cisco TAC, specializing in Layer 2 technologies such as spanning tree. After his stint at Cisco TAC, he has held several roles across different organizations, with functions including escalation support for enterprise and data center engineering, designing, implementing, and troubleshooting enterprise and data center networks, technical marketing for Cisco Software Defined Access (SDA), and technical marketing for Juniper Networks data center business unit, while also focusing on multi-vendor interoperability in data centers.
In his current role as a principal network engineer at Nokia, Aninda specializes in the design and deployment of data center networks with EVPN VXLAN, while also focusing on the high demand of networking infrastructure for high-performance computing and AI/ML clusters. He also leads the validated designs workstream, ideating, building and testing validated designs for general-purpose data centers and AI infrastructure at Nokia.
Aninda actively writes on his personal blog, www.theasciiconstruct.com and teaches at www.networkfoundry.tech.
