Eagle - How to make Single Sided PCB

Hi
I recently read a tutorial on Eagle & got to know atleast the basics of making a PCB design using software.
The auto-route feature in Eagle gives an efficient layer of tracks for a double-sided PCB. However a double sided PCB is very costly as compared to a single sided one (almost 5 times the price). I would like to know if there is any setting in the software, so that it maximizes the tracks on any one side, so that the few tracks on the other side can be connected using wires. (Normally there are approximately an equal number of tracks on both sides.) If there is any other s/w other than eagle which has this kind of single sided auto-routing feature, please let me know.

Thank You…

In the auto options set layer 1 to *, layer 16 to N/A

or you can set layer1 to N/A, and do nothing to layer 16 so you get blue line track!

But could you tell me what N/A means or stands for?

Hi
Thanks for replying. I tried both methods suggested by 4elektros & msahmed. But both are not working. I still get blue as well as red layers i.e. double-sided PCB.
Kindly help

Any layer turned to N/A will never be routed upon. If it is not working, there is something seriously wrong.
