Cisco Nexus EVPN VXLAN Hands-On Guide

By: Wansoo Kim

Cisco Nexus EVPN VXLAN Hands-On Guide is the practical, hands-on guide to understanding and building EVPN VXLAN data center networks in a real Cisco Nexus environment. Starting with the fundamentals of VXLAN, the book takes readers step by step through the design, configuration, verification, and troubleshooting of an EVPN-based data center fabric.

Rather than focusing solely on theoretical concepts, this book is built around hands-on labs validated in actual Cisco Nexus environments. It covers the key components and technologies that engineers encounter in real-world deployments, including Underlay and Overlay networks, MP-BGP EVPN Control Plane, VXLAN Data Plane, Anycast Gateway, vPC, External Routing, Ingress Replication, Multi-Site, and TRM (Tenant Routed Multicast).

One of the key strengths of this book is that it explains not only how the network is configured, but also why it works the way it does. Through detailed Packet Walks covering ARP, Bridging, Routing, and Silent Host scenarios, readers can follow how packets are encapsulated, forwarded, and decapsulated throughout the fabric. The book also explains how routes and MAC/IP information are learned and distributed through the EVPN Control Plane, helping readers understand the relationship between the Control Plane and Data Plane.

The labs go beyond basic configuration. Each topic follows a practical workflow of Configuration, Verification, and Troubleshooting, allowing readers to build the environment, verify its operation, and analyze unexpected behavior. Advanced topics such as Flood and Learn versus BGP EVPN, Route Learning, vPC and Orphan Hosts, MAC/IP Duplication, DHCP Relay, Multi-Site, and TRM are introduced progressively so that readers can develop a solid understanding of the overall architecture and its real-world behavior.

The final chapters focus on troubleshooting and operational techniques, covering tools and methodologies such as NGOAM, Ethanalyzer, ELAM, and iCAM, along with real-world failure scenarios and case studies. These sections are designed to help network engineers move beyond simply checking whether a configuration is correct and instead understand how to identify, analyze, and resolve problems at the packet and Control Plane level.

Cisco Nexus EVPN VXLAN Hands-On Guide is designed for both network engineers working on data center design and operations and readers who are new to EVPN VXLAN. By combining fundamental concepts, hands-on configuration, packet-level analysis, verification, and troubleshooting, this book provides a practical path from learning the technology to applying it in real-world environments.

For anyone who wants to go beyond simply configuring an EVPN VXLAN fabric and truly understand how it works-from the Control Plane to the Data Plane and from configuration to troubleshooting-this book is a practical guide for building that expertise.
