Hi Mic,
I know on ATT ATM-to-Frame-Relay networking they tell you not to use CDP. I
tried using it anyway, (of course) and couldn't get it running.
HTH,
Sean

CDP should be disabled on remote frame ints because their FRATM switches
will choke on resulting encapsulation failures. Doesn't seem to matter
whether it is Transparent or Translational, (though CDP appears to fail for
different reasons, depending). I know NewBridge's have this problem.
