My question :

> first ethernet card as ip address 202.35.81.100 (netmask 255.255.255.0)
> second one has IP address 202.35.82.222 (same netmask)

Thanks all,

I finally decided to create a boot script /etc/rc3.d/S12routedelete (a
link to /sbin/init.d/routedelete), which delete the unwanted route at
boot time.

I was suggested to remove the route info from /etc/routes file, but
unfortunately, this route was not mentionned in this file.
I still don't know how and when exactly the routes to my 2 subnets are
defined, but I found a workaround..
