Vlan trunking on extender mode

Hello all,

Im planning on buying 2 Asus AC68U models, on will be connected to the main modem of my isp wich gives me a trunk.
One VLAN for internet acces and one separate VLAN for IPTV.
If i place the second the AC68U in extender mode upstairs will the extender mode see both VLAN's and can i asign them the same as on the main router, port 3/4 for IPTV and ports 1/2 for internet acces?

Regards,

Mini
