The Basic Steps to Set up DCI with EVPN VXLAN Overlay Step 1: SDN local controller takes over local DC network control from Neutron, and provides plugin for Neutron Step 2: SDN local controller instructs local DC-GW to set up EVPN and create VXLAN tunnel with remote DC-GW Step 3: Local network is connected to remote DC with EVPN VXLAN overlay (see details in the next two slides)
