Workbook 2 - Lab1 - QoS
Just stumbled upon this - in the solution we are told how to calculate the bandwidth needed for 8 calls but we are using the regular Frame-Relay overhead of 4 bytes for this.
In task 1.29 however we are asked to use fragmentation. According to QoS Enterprise Guide on page 1-15 (or 33), it is said that the FRF12 header is 8 bytes long. So going forward, the entire calculation is wrong as it is based on an 4 byte FR Header instead of 8, correct?
Another thing is when we are talking about the shape values in task 1.28. It's said Cisco recommended value is 95% of the CIR, which is 768000 (* 0,95 = 729600) but the Bc should be CIR/100 and that would be 7680 but in the solution, Mark is using 7600. Just a typo or am i missing something?
