Ed,
Read the requirement again, take note of this statement - "In order to
ensure that critical traffic transiting your network gets the best
service possible.....".
By configuring IPP 6 & 7 with same drop thresholds and probability,
IPP 5 does NOT get the best service possible, it gets better service
than IPP 1-4 but *the same* service as IPP 6 & 7.
