You cannot modify the AD of a remote router through update packets (someone
correct if I'm wrong). On the remote routers you can try and modify the
default-cost and general bandwidth using the router-config command
"auto-cost reference-bandwidth". Look through the IP command book on CCO,
you will find all your answers there. Remember that you can modify the
routers view of the connection, make it high speed or low...
I take it that your getting ready for the lab. I recommend that you start
learning how to do things in many different ways. The suggested solutions
are usually the simplest and easiest methods to the solution, I doubt if
they (Cisco) are going to want to know how to do things in a straight
forward manner. Cisco exams are probably written by lawyers so I think you
should expect to find questions like do this and do that but you cannot use
the following methods and some methods will only cause problems later on.
I recently went through a similar thing with frame-relay and isdn.
When is your exam by the way?
I think I killed a brain cell...only 1 left
