A comprehensive guide covering VXLAN fabric technology from Layer 2 fundamentals through advanced data center and campus fabric architectures. Designed for network engineers, students, and professionals preparing for consultant-level interviews.
This guide walks through the full journey from traditional VLANs to modern VXLAN fabrics:
- Layer 2 Fundamentals - VLANs, CAM tables, First Hop Redundancy Protocols
- VXLAN Concepts - VXLAN fundamentals, VLAN vs VXLAN comparison
- Fabric Architecture - Clos/Leaf-Spine architecture, Underlay and Overlay networks
- Control Plane - BGP EVPN fundamentals and route types
- Traffic Flow - Intra-VXLAN, Inter-VXLAN routing, BUM traffic handling
- Multicast in VXLAN - Multicast groups, VNI-to-multicast mapping strategies
- Anycast Gateway - Distributed gateway as FHRP replacement
- Vendor Implementations - Cisco DNA/SD-Access and Juniper Campus Fabric
- External Connectivity - Fusion router integration and external traffic flow
- Hands-On Labs - Step-by-step labs for Cisco (NX-OS, DNA Center) and Juniper
- Interview Preparation - Questions and answers from basic to consultant level
