We are testing right now in our lab the new qfx5120 We are only waiting the official software release ...
The box is here already The specs only shows L2circuit ... but we are waiting to see flexible ethernet encapsutation ( no vpls we already know ) to use vlan and mpls at the same interface. But the main ideia is to use it with evpn/vxlan configuration and try qinq in vtep After that we can post the results here Att Giuliano C.
