Brian,
Those are my solutions. I just wanted to get an idea what might be wrong with it. Below are the configs for the actual solution, which I just don't understand. I would definitely be interested in the vSeminar.
Thanks,
Danny

Danny,
Are those your solutions to the scenario? The solutions are allowing the router to send data at 64kbps for DLCI 101 and 256kbps for DLCI 102. The router will overwhelm the interface since the AR (aka port speed) is 256kbps. Also configuring min-CIR does not do anything if adaptive shaping is not enabled.
Below is a link to a Frame-Relay traffic shaping presentation I developed. Read it over and let me know if you have any questions. It should help clarify FRTS.

If we can get a few people to sign up I'm willing to do a free Frame-Relay traffic shaping vSeminar next week.

Subject: FRTS scenario
Hello Group,
A scenario for FRTS on a lab that I'm doing states:
"Assume voice traffic is will be passing over dlci 101, which has 64k link speed. Configure Frame Relay such that there is no latency and packets are not dropped. DLCI 102 has 50% BW of port speed. Configure CIR, Bc and Be accordingly by maintaining Tc's default value and interface queueing default mechanism. Port speed Between r1 and r2 is 256k."

dlci 101 | | dlci 102

R2
Here's what I have as far as configs. I get all sorts of different answers for what this should be. Hopefully I can get this cleared up. You think you understand something, and then you get punched in the mouth.
Thanks,
Danny
