If your goal is to have your DHCP client not use the default gateway
that the DHCP server gives you, you can override this by creating an
/etc/dhclient.conf file and place a line in that file that reads
something like:
supersede routers "my.default.route.ip" ;
You can "man dhclient.conf" for more info and a full sample to start
from. Another option would be to give your host a static reservation in
the DHCP server, and have that reservation not give out a default route.
