2. Discussed the updated version of network diagram on wiki. Underlay network between two PEs is MPLS L3VPN; and from DC-GW to PE is VLAN. VXLAN overlay is set up between two DC-GWs by EVPN. VTEP is on DC-GW. DC-GW is controlled by SDN local controller provided by vendor.

4. Discussed the solution that SDN local controller provides some APIs to map DC-side VXLAN with WAN-side VXLAN on DC-GW. Chengli will provide the SDN local controller APIs which CMCC used in its lab to set up VXLAN tunnel with EVPN. Based on that information, we will provide a diagram on wiki to illustrate how the VXLAN mapping is done.
5. MultiVIM project proposed to handle DC-GW through SDN local controller and expose APIs for ONAP to set up Depend on the interface and capability of SDN local controller, we will decide in the next meeting how modules (MultiVIM, Neutron, SDN local controller, SDN WAN controller, DC-GW) work together to provide VXLAN overlay between data centers via EVPN.
