[j-nsp] QFX5110 : Q-in-Q in VXLAN

[Raphael Maunier]

I was about to suggest this .

If you only need to do A to B, I will suggest doing pseudowire instead of Evpn transport.
But, you cannot end the pseudowire on a sub-if ( on MX you can ), on QFX, Interface are dedicated to one protocol

    Thank you for your answers, very bad news for me :(
    There's no solution to make a transparent pseudowire with support of VLAN
    tags with my hardware ?
