This article outlines fundamental design principles for data center networks—scalability, availability, flexibility, and security—and examines modern topologies such as Fabric with M‑LAG, Overlay, Spine‑Leaf, and BGP‑EVPN, while also highlighting emerging trends like high‑bandwidth SDN, heterogeneous compute clusters, and intelligent, cost‑effective operations.
This article compares traditional three‑tier data‑center networking with modern leaf‑spine IP‑Fabric architectures, detailing bandwidth, availability, scalability, security, and the advantages of BGP EVPN and VXLAN in terms of scalability, convergence, multi‑tenant support, automation, and overall cost.
This article explains the different VXLAN control‑plane options, focuses on the BGP EVPN approach, and provides a step‑by‑step Linux lab using FRR to configure VTEP devices, establish route‑reflector sessions, and verify MAC and FDB propagation across the overlay network.
This article explains how VXLAN overcomes traditional data‑center network limits on VM scale, isolation, and migration by using MAC‑in‑UDP encapsulation, a 24‑bit VNI, and BGP EVPN control plane, and shows its practical deployment in cloud‑campus environments with gateways, VTEP, NVE, and VBDIF.
This article provides a comprehensive overview of VXLAN, explaining its purpose, architecture, frame format, VTEP implementations, and advantages over VLAN, Q‑in‑Q, MPLS, and other overlay protocols, while also discussing control‑plane options such as BGP EVPN and SDN automation for modern data‑center networks.
This article explains how VXLAN technology overcomes traditional data‑center network constraints—such as limited MAC tables, VLAN isolation, and VM migration scope—by using MAC‑in‑UDP encapsulation, VNI identifiers, and BGP EVPN control, and demonstrates its practical deployment in a CloudCampus solution.
