I have just turned up two t1 lines hooked into two AdTran NetVanta 3430 routers. While the NetVanta boxes seem fine, what I really want to do is to configure some of my old Cisco boxes to handle the T1s rather than bridging from the AdTran boxes to the Cisco boxes.
The problem I'm having is that I'm not quite sure how to get CHAP working properly with the Cisco boxes to allow the Cisco boxes to connect via their serial interface and get and IP established upline dynamically. I already have yet another T1 which has a fixed IP setup I implemented a number of years ago, and that has been working just fine, unfortunately, I'm not sure I can get my vendor to provide the static upline option for the new circuits, thus this post.
Any thoughts would be greatly appreciated. I'll post the AdTran configuration to follow:

Even just a skeletal Cisco translation is greatly appreciated. In other words, something like the CHAP stuff in ppp belongs on Cisco interface x, the bvi should be a subchannel of the serial interface... Just need a few clues, as I cannot find any similar configurations for the Cisco which do CHAP, point-to-point frame relay for t1, despite a fair amount of time in search engines over the past week.
Heck, I'd be very grateful for a link to a configuration like the AdTran.
Thanks in advance, if there is anything else needed to point me in the right direction, I'll be happy to post a follow on to supply it.
