Configuring Cisco 2501

It must have been more than 6 years since I last configured a Cisco router. My knowledge on IOS is so rusty already that I had to resurrect some old config files from my Planet days that I burnt onto CD for posterity sake. I sold a second-hand Cisco 2501 to my uncle's company so I had to re-live my Cisco days and configure it to see the telco's router via ppp encapsulation. It wasn't so bad though. I got it to ping the other router after just copying-and-pasting some old config file!
