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.
