This is a demonstration on how to use subinterfaces to route DHCP using vlans. This project uses 1 Router, 3 Switches, and 3 Computers. Each switch is trunking all vlans.
There's no need to use the 'no shutdown' command in the Sub Interface... when you do it in the physical interface it drops all the sub int :P just saying....
@InsaneMetalSoldier Your correct, on the initial setup you do not need to bring the sub-interfaces up. Just a habit I guess.
On the other hand if the configuration is already done, the sub-interface can be placed in shutdown mode, so i find its useful to make sure all ports are up.
