This article explains the fundamentals of VXLAN, compares it with VLAN, and provides step‑by‑step Linux kernel and Open vSwitch implementations, including configuration commands, packet‑flow analysis, and practical testing to demonstrate overlay networking in cloud environments.
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 VXLAN's role in cloud networking, details its 24‑bit VNI architecture, shows how Linux kernel and Open vSwitch implement VXLAN tunnels, and provides step‑by‑step command examples and flow‑table configurations to achieve overlay networking across multiple hosts.
This article provides a comprehensive guide to VxLAN technology, covering its architecture, tunneling mechanisms, NVE/VTEP roles, L2/L3 gateway designs, MTU considerations, and the integration of EVPN MP‑BGP with detailed explanations of route types and deployment scenarios.
VXLAN (Virtual Extensible LAN) is a network‑virtualization overlay that encapsulates Ethernet frames in UDP packets to create logical Layer‑2 domains over IP networks, enabling seamless VM migration, massive tenant isolation, and flexible gateway designs, while EVPN provides a scalable control plane for dynamic tunnel management.
This article explains the fundamentals of VXLAN, its tunnel-based architecture, why it is needed for virtual machine migration and multi‑tenant isolation, how it differs from VLAN, the packet format, VTEP and VNI concepts, tunnel establishment methods, gateway types, and detailed forwarding processes within both centralized and distributed VXLAN deployments.
This article explains VXLAN technology, covering its definition, tunnel architecture, VTEP and VNI concepts, differences from VLAN, packet format, tunnel establishment methods, gateway types, and detailed forwarding processes for both same‑subnet and cross‑subnet communications in data‑center networks.
