I currently have a 3 tower setup with pppoe from a rb1000 on the ground. Can I setup a vlan on all 4 routers and bridge it with my ap interface? I am currently using eiop tunnels and it is working but I would like to simplify my setup and hopefully take the eiop overhead out of the equation. I am very proficient with networking and vlans but have not found a way to set some of my links as trunk interfaces. I have to be just missing something easy.(do I have to tag the vlan on all interfaces?) Here is my setup

RB1000(pppoe server and gateway) ------RB750g------RB493AH-------RB433AH-----RB433AH

All the links are routed

I just figured out how dumb this question is. Its been a long week
