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 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). ip fabric success stories
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. VXLAN with EVPN Type 5 routes (IP prefixes, not just MACs)
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. For any organization building or renovating a data
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).
