Cisco router configuration newbie

[Guest_imported]

Our Frame Relay provider just called because they want us to change our WAN address and gateway on our Cisco 2500 Series router. I've never configured a router before and nobody knows what PC was originally used to configure it. So I assumed if I downloaded Config Maker from Cisco's website, I'd be able to use that. I installed it on a computer but I'm not sure how to use that program to change the IP address. I used the Auto Detect Device feature and it finds the router and gives me a log on page. I log on to it but don't know what to do from there. In some sections it doesn't show anything being configured on it and in others it shows the IP addresses on it and everything and when I close the program it asks me if I want to save changes. It looks more to me a way to make a diagram and not change configuration. I'm afraid if I do anything I will lose all the configuration. Please help me! I'm not sure how they configured this router before, whether through Config Maker, Command line or what???

Hi Desilu,

The easiest way would be to telnet to the router and first make a copy of the config (simply enter <write term> and copy the output or log the file to a notepad file. Now enter the following commands:

Conf term
interface serial x (0 or 1)
ip address <whatever your provider gave you>
exit
exit

I guess you'll also need to change the routing statement to do this do a write term and look for a statement <ip route.......> Copy this line and do the following

conf term
no <paste here>
ip route 0.0.0.0 0.0.0.0 <provider assigned address>
exit

This should now work. If it helps send the old config and new interface bits direct to me at stevep@cisco.com and I'll send you instructions. HTH
