Hi,
I currently have a T1 internet line with a Cisco 1720 router (Came with ISP), and I have a spare Cisco 2610. I am trying to configure this spare router exactly as the 1720 router, and when I plug the cable to this spare router WIC DSC T1 card, the light turn green, so the serial link is OK. I plug a pc to the router ethernet port, and I was able to ping the router e0 ip address. However, I was not able to ping the ip on the serial0 interface and couldn't get out to the internet. Why can't I even ping the Serial0 interface ip address? I compare the configuration on my Cisco 1720 and Cisco
2610, and they are exactly the same? Did I configure something wrong on my Cisco router (I made up the ip address, not the real one assigned by my ISP)? His is a "Show Version" and "Show Running-Config" on my Cisco 2610 router. Please tell me what I did wrong.Thanks, Alan
