In addition to using the 'max-reserved-bandwidth 100', you also need to
verify that the bandwidth on the interface is properly set to 6000 with the
command bandwidth 6000. If the router thinks that there is 10Mb available,
the router would allow 2Mb for the class with 20% allocated.
20% and 80% are not accurate percentages if your speeds are 1M and 5M on a
6M line. 20% of 6Mb would be 1.2, and 80% would be 4.8.

Importance: Low
Infact the HQ use 6M WAN ethernet line connect to two
offices. One office was 1M line and another was 5M.
I want to set the shaper function on the HQ's router.
If I use the "max reserved-bandwidth 6000" command on HQ
router, may I do it ?
I also worry about one question, eigrp will run between hq
and remote office, if I shape the 100% bandwidth to two
remote offices , does it bring some trouble to eigrp ?
thanks alot
