CBWFQ and PPP Multilink

[uhaskamp]

Hi all,

I have tried to configure CBWFQ and PPP Multilink on an ISDN BRI interface

with DDR. The dialer load-threshold is set to 1 so that both b-channels of the BRI interface are connected when the link comes up.

I need a traffic class with a minmum of 80Kbit/s on this link, but largest bandwidth I'm allowed to configure is 48Kbit/s .

I have tried it directly on the BRI interface and with a Dialer interface.

Both the same effect. When I configure the policy-map into a Dialer interface the policy is also configure to the attached physical links and there the smallest availabe bandwidth is 64k regardless of how many links are configured for multilink.

The configured bandwidth on the BRI is also set to 128k.

So, does anyone know a trick to configure a class with 80k on a DDR/PPP multilink connection which persists of several ISDN b-channels.

Thanks for twist your minds. :-))

Try giving the required bandwidth in percentage

I think this URL explains a problem that looks similair to yours, hope this helps.
