Would you also post the output of show protocol from the 7206? I notice on the 2600 show interface that CDPCP is closed and on the 7206 that CDPCP is not present. Is CDP disabled on the 7206 interface? If so would it be possible to enable CDP long enough to get the output of show cdp neighbor detail from both routers? I also notice that on both routers the show interface does not indicate that IPCP is present. It should be present to run IP on the interface. I am puzzled why IPCP is not present. Would you be able to run debug ppp negotiat, shut down the interface, and then no shut the interface, and capture any debug output and post it (at least on the 2600 if you can not do it on the 7206)? Thanks for posting this information. Would you also post the output of show protocol from the 7206?

On the 2600 side it looks ok and I do not see anything that looks like a problem. Perhaps you could post similar data from the 7206? When you do show ipx route do you see any routes on the 2600 that are learned from the 7206? This would be one way of demonstrating that the serial interface was working. I also wonder if CDP would tell us anything useful? Although I notice that CDPCP is not open and wonder if CDP has been turned off. Thanks for posting the additional information.
