I am trying to practice setting up frame relay to study for my ICND exam. The labs I am reading through are using an 'Adtran Atlas550 Frame Relay emulator' to simulate the frame relay cloud.
I currently have 3 routers, 2 x 2501s and a 2503 - all have an 1 x ethernet and 2 x serial interfaces. Can I create a frame relay cloud with what I have? Or do I need to buy another router with more serial ports?
If I need to buy another router - will a 2522 do? The one I was looking at has 2 x serial and 8 x low speed serial interfaces. Will I be able to plug the serial from the 2503/2501s into the low speed serial interfaces on the 2522?
Should I not bother and just use a software simulator like dynamips?
