Hi, Given the following two variations of the same setup: HostA ------------------ HostB eth0: eth0: 1.1.1.1/24 1.1.1.2/24 2.2.2.1/24 2.2.2.2/24 and: HostA HostB eth0:1.1.1.1/24 ------------ eth0:1.1.1.2/24 eth1:2.2.2.1/24 ------------ eth1:2.2.2.2/24 (basically same setup but with two NICs on each host) How does one set up advanced routing so that when HostA sends a packet from 1.1.1.1 to 2.2.2.1, it goes via HostB, and vice versa: a packet from 2.2.2.1 to 1.1.1.1 also goes via HostB. This setup would allow me to do traffic-generator/ troughput-like tests when HostB is a low-end machine. I have been fiddling around with ip route/ip rule, but the biggest problem I seem te be having is that when I change/delete an entry from the local table, HostA no longer replies to ARP queries on the wire. Thanks in advance, Filip

Linux is way to smart for this to work otherwise :-) Regards, bert -- http://www.PowerDNS.com Versatile DNS Software & Services http://www.tk the dot in .tk http://lartc.org Linux Advanced Routing & Traffic Control HOWTO
You can enable Zebra routing because both host are in different networks maybe ripd a possible solution this issue http://www.guadawireless.net -.-.LievenX..--. ----- Mensaje Original ----- De: bert hubert <ahu@ds9a.nl> Fecha: Jueves, Julio 4, 2002 4:49 pm Asunto: Re: [LARTC] advanced routing for traffic generator-like setup> On Mon, Jul 01, 2002 at 02:14:22AM +0200, Filip Sneppe wrote: > > > How does one set up advanced routing so that when > > HostA sends a packet from 1.1.1.1 to 2.2.2.1, it > > goes via HostB, and vice versa: a packet from > > 2.2.2.1 to 1.1.1.1 also goes via HostB. > > Only by doing NAT at HostB.
