I was talking about the rate. The ceil must be 128kbit/s so they can bor=
row=20
up to 128kbit/s. =20

That's no problem IF you follow some basic rules. You can find them on=20
www.docum.org on the faq page. You have to see the ceil as a maximum of =
the=20
class. And the rate as a minimum bandwidth and a "divider". =20
The other problem is the parent rate and ceil. I did some test and I hav=
e=20
strange results. I still have to find a way to find out how you can=20
configure the parent rate and ceil to get a good setup.
