Deployment Guide

6 Dell EMC Networking Virtualization Overlay with BGP EVPN
1 Introduction
Our vision at Dell EMC is to be the essential infrastructure company from the edge, to the core, and to the
cloud. Dell EMC Networking ensures modernization for today’s applications and for the emerging cloud-native
world. Dell EMC is committed to disrupting the fundamental economics of the market with an open strategy
that gives you the freedom of choice for networking operating systems and top-tier merchant silicon. The Dell
EMC strategy enables business transformations that maximize the benefits of collaborative software and
standards-based hardware, including lowered costs, flexibility, freedom, and security. Dell EMC provides
further customer enablement through validated deployment guides which demonstrate these benefits while
maintaining a high standard of quality, consistency, and support.
This guide provides a step-by-step deployment example of Border Gateway Protocol (BGP) Ethernet Virtual
Private Network (EVPN) for Virtual Extensible LAN (VXLAN) using Dell EMC PowerSwitches and PowerEdge
servers. BGP EVPN for VXLAN is used as a network virtualization overlay to extend Layer 2 connectivity
across the data center, allow for a greatly increased number of Layer 2 domains, and to simplify Virtual
Machine (VM) migration.
The environment includes a physical Layer 3 leaf-spine topology underlay and three overlay virtual networks.
Two virtual networks use anycast gateways, and the third uses an indirect gateway.
VMs running on VMware ESXi hosts are used to validate this environment and to demonstrate tunneling
Layer 2 virtual network traffic through a Layer 3 leaf-spine network. Traffic is sent between VMs on the same
and different virtual networks and to the external network or Internet. The virtual networks using anycast
gateways demonstrate integrated routing and bridging (IRB). The virtual network without an anycast gateway
tunnels through the leaf-spine network to get to the indirect gateway.
