No. The iproute2 utilities allow to set various things, such as ip addres= ses,=20 routing entries or the traffic shaper. The iptables tool is responsible for the firewall and the rules in there = - as=20 well as some packet mangling and network address translation. You can com= bine=20 both tools with the -j MARK directive .. rtfm ;-) - Thilo Schulz --__--__-- Message: 3 Date: Tue, 20 Aug 2002 22:32:13 -0500 (CDT) From: Amit Kucheria <amitk@ittc.ku.edu> To: lartc@mailman.ds9a.nl Cc: stef.coene@docum.org Subject: Re: [LARTC] HTB equivalent for 'bounded' and 'isolated' in CBQ On Fri, 16 Aug 2002, Stef Coene wrote: >> The 'ceil' parameter allows us to implement a part of the 'isolated' >> definition above.

Just like the definition of isolated :) What happens when there is no traffic in class 1? Will class 2 and 3 share class 1's bandwidth then? The reason I am asking these questions is because I am trying to see if HTB can be used in place of CBQ in Diffserv. Has anybody tried something like this? Regards, Amit -- I'm an angel!!! Honest!
