I believe the workbook changes the K values using metric weights 0 0 0 1 0 0
to cause the routers to only use delay to calculate the metric. This
simplifies the calculation and should make this a simple process if you know
how to display the interface delay for each hop. You can also just leave
the K values to default and play around with the metrics until you get it
right, which although not really very scientific still works.
