Folks, I am really new at this because of a recent departure of our Cisco guru. Here is what I am attempting to do. We just moved someone from one building to another and switched them from our ADSL network to a T1. I am trying to configure the Serial Interface on our 3660 to support that connection. I have another Serial port setup previously with a similar connection. I have made the serial port I am attempting to configure the same as the other one except for the IP information. Now, Here's the question. By looking at the "Show IP Route" command results, I see that the original Serial interface says "IP is directly connected, Serial4/0. How can I do the same thing with the new connection that is going to be connected to Serial4/2? What is the command to make this happen? Please help me Obiwan, you are my only hope.
