Re: L2 and L3 deployment.

Layer 2 means the user gateways are upstream in a switch/router and the controller is dot1q trunked (or access if single VLANs) to the upstream switch.

 

Layer 3 means the controller holds the L3 gateways and usually routing is in use.

 

Layer 2 is the most popular design.

No, not really. It's more about traffic flow.
