Apologies if I misunderstood you.
When I see the below in the same sentence, I had to ask the question:
i know there are expensive software sabre , aims and other. Im looking for simple tool to download from internet or something cheap like 100 or 200 us dollar just to build routing
If you want to do this correctly, my advice would be to steer clear of cheap tools. Investment pays off in the end.
Just my opinion you understand.
