Al: Can you tell us WHY you want the kernel to use a lesser match? By design, it uses the route that matches the most bits. You have an 8 bit match on the eth0 route and a 24 bit match on the eth1 route. If you want to change the way route decisions are made, you can create your own routing tables and use policy routing to enforce any arbitrary routing policy you choose. Look up the ip rule command in the iproute2 documentation. It appears that this command will allow you to do what you appear to want to do.
