Marko, Tyson, Quick question if you don't mind. I apologize if this has been explained before I must have missed it.
Volume 3, Lab 4, Task 1.4 says Ensure that both R7 and R8 consider this link to have 2000Kb/s available. configure appropriate bidirectional rate-limiting on R8. Do not use the MQC. When I took this lab, I zeroed in on the fact that this was asking for GTS. However in the solutions guide, you configured it on the physical link rather than the PPPoE link that was asked for earlier in task 1.4. I am curious what might have clued me in to put it on the physical instead of the dialer interface? But the big question is this, I cannot seem to come up with the numbers you used for the rate-limiting and I am curious if the proctor/grading script will be this picky (is it wrong if you don't use the values for BC/BE that they would?) The video on demand lesson for this says: AR=access rate = line speed not cir CIR=target rate for rate limit command BC=TC*CIR BE=AR-(TC*CIR) TC=1/8 sec or .125 sec The solutions guide used the command: rate-limit input 2000000 375000 750000 conform-action transmit exceed-action drop Backing out your numbers from the above formulas, I get a TC of .1875 and a AR of 1125000 see below, I cant figure out where those numbers would have come from. Can you shed some light on that for me. BC=375000=.1875*2000000 BE=750000=1125000-(.1875*2000000) Thanks Patrick A.
