Ip Fabric Success Stories ((new)) May 2026

A dual-leaf IP Fabric with intelligent load balancing. Using VXLAN with native ECMP (as opposed to static LAGs), the fabric performed per-packet or per-flow load balancing depending on configuration (e.g., flowlet switching).

A leaf-spine IP Fabric using VXLAN-BGP EVPN. 4x Spine switches (100GbE), 48x Leaf switches (25GbE to servers, 100GbE to spines). Orchestration via Ansible and a Network Source of Truth (NetBox). ip fabric success stories

Note: This paper synthesizes documented outcomes from publicly available case studies from Arista (e.g., Microsoft, LinkedIn), Cisco (e.g., eBay, PayPal), Juniper (e.g., DreamHost, Riot Games), and open-source SONiC deployments. A dual-leaf IP Fabric with intelligent load balancing

A white-box IP Fabric running SONiC (Software for Open Networking in the Cloud). 64x 100GbE spines, 256x 40/100GbE leaves. VXLAN with EVPN Type 5 routes (IP prefixes, not just MACs). 4x Spine switches (100GbE), 48x Leaf switches (25GbE

For any organization building or renovating a data center network today, the question is not “Should we deploy an IP Fabric?” but rather “How quickly can we decommission our legacy core to deploy one?” End of paper.

An IP Fabric with EVPN Multi-Homing (ESI – Ethernet Segment Identifier). The fabric stretched the legacy VLANs across a DCI using EVPN Type 2 routes over a WAN.
