Sorry, you're right, I'm completely off base.  Forget iptables, you're
asking about
 iproute2.

You can save your ip route commands in the
/etc/sysconfig/network-scripts/ directory
 files for each interface route-ethX.  They will then be automatically
called when the
 interface is brought up on reboot, or with 'service network restart'.

IIANM, simple put all args after 'ip route add' as individual lines in
the file(s).

I hope this is actually helpful this time.
