How is eth0 getting it's address? If it's by DHCP then that would be the cause of it. The router involved is probably to blame.
To keep your maching usable you could write a script that looks for such a route and if it exists removes it and logs the problem. A script like that running from cron can keep it accessible.
If you can set your eth0 to statically configured, that should also prevent it from accepting routes via DHCP. If necessary, you could also add firewall rules to drop DHCP packets arriving via eth0. Hope that helps, Andrew
