Hey there, sounds like you are a perfectionist :-)
Either way would work, however I prefer YOUR answer. Unless the question
states otherwise, I use defaults. The default Bc value is 7000. I would have
left the Bc to this value, as you have done.
In practise, all this does is changes the Tc. With a Bc left to default, the
calculations are as follows:
Bc/CIR = Tc
7000/32000 = 218ms. Therefore, you can send 7000 bits, every 218ms to
achieve a CIR of 32000 bps.
In the answer, the values are:
4000/32000 = 125ms. Therefore you can send 4000 bits every 125ms. As you can
see, both achieve the same CIR.
Hope this helps
Dazzler

A traffic shaping question on one of the workbooks states
Configure R1 to use traffic shaping to reduce flow when BECN's are
detected. Average rate is 32K min should be 8K. Port Speed is 64000
bits/sec
The solution had BC configured. Is this required? If I don't configure
Bc will I lose points.
Thanks
