In trying to configure routers, I get to the part of configuring the serial port, and no more than 30 seconds, it auto. goes down! I have tried several times(running into days) to get several serial ports to work (after no shut command) and no matter what they always go down 
- has anyone else run into this problem? I do understand it can bee a keepalive problem, but that is not disabled- is it recommended to place a clock rate on each and every config? And for the purpose of the sim, I'm not sure it's an encapsulation problem. Any assistance is quite helpful- and yes I have e-mailed the company twice--so far..

Someone asked me when will my studying be over......

I ran into a similar problem. My serial interfaces would go down within seconds of of doing a "no shut" What fixed it was setting the clock rates on whichever device/interface was controlling it. Once I did that everything stayed on and worked just fine.
I was recreating the network map shown in the Sybex Deluxe book and got stuck when setting up those serial interfaces linking the three lab routers together. Once I set the clock rates on the middle router... everything stayed up and working. Not sure if this is the same situation. Thought I would throw in my 2 cents.
