 +        * usage: user friendly zone names instead of ''vmbrX'' interfaces. But still needs to specify VLAN tag for VLANs. 
 +        * DHCP server and IPAM possible for zone 
 +        * Outbound NAT to internet provided locally by each node
       * **VLAN**        * **VLAN** 
-      * **QinQ** +        * like above but with VLAN tag assigned 
-      * **VXLAN** +      * **QinQ** - 802.1Q tunnelling / stacked VLANs / 802.1ad 
-      * **EVPN**+        * first VLAN tag in L2 frame is a provider / service vlan  
 +        * 2nd VLAN tag in L2 frame is customer tag 
 +      * **VxLAN** RFC 7348 (tech preview)  
 +        * encapsulate L2 frames in L3 UDP packets. 
 +        * L3 networks solves lots of forwarding/routing problems of L2 networks. No STP nor VLANs needed. 
 +        * well known protocols like OSPF, EIGRP can be used for L3. 
 +        * VNI tag is 24 bit (16 777 215 VxLANs) 
 +        * one VxLAN is a group of Virtual Tunnels. VTEPs (Virtual Tunnel Endpoint) acts like switch
