Thanks Nick. 'Preciate the feedback.

I have forged ahead with traffic shaping and read a few additional articles fro
m Cisco's web site. Still having a bit of a hard time with Bc, Be, CIR, and CI
RMin. To me they appear redundant. None-the-less while trying to configure an
d test a configuration on a 2500 router traffic shaping does not activate. I h
ave tried the configuration under a multipoint interface and a physical interfa
ce; neither worked. From what I can tell the following is a text book configur
ation based on Caslow's book. However, under the 'show frame-relay pvc 130" co
mmand it states that traffic shaping is not enabled. When streaming packets th
e counters for BE and DE never increment. I have also tried restarting the rou
ter. Below is the IOS version, fragment of the configuration and the output of
 the show command. Any thoughts?
