I am pretty much a novice as far as router configuration goes. We have just purchased two Cisco 1841 routers with the T1 interface. I have them configured, but am trying to test the communication between the two routers before shipping the one to the other side. I have created and attached a T1 cross-over cable to the serial interface on both routers. The modules are showing green (CD) and have no alarms now. The problem is I am trying to ping the interfaces and am having no luck. Here is the current situation:
Router 1: FA0/0 - 192.168.12.10
Serial0/0/0 - 192.168.15.2
Router 2: FA0/0 - 192.168.9.10
Serial0/0/0 - 192.168.15.1
From Router 1: It can not ping it's own serial interface (15.2) and it can not ping the FA0/0 interface on the other router. It can ping the serial interface on the second router.
The same is true when trying to ping from router2.
What am I doing wrong and what can I try?
Attached are my configs. Any help or suggestions you can offer is appreciated.
