Correct. Make sure you have the line "ONBOOT=yes" in each ifcfg-eth*
entry.

>/etc/ifconfig/network?

I assume you mean /etc/sysconfig/network?

No, you can't. Are you sure you want to, though? Remember that's
defining the default gateway, and you'd generally only want one
of them. The network startup scripts will automatically add a
route to each locally attached network, so you don't need to do
it explicitly. If you genuinely need multiple default gateways,
or if you have additrional routes you want to add, you can stick
them in /etc/sysconfig/static-routes (which has a fairly bizarre
syntax that I can't remember off the top of my head -- it's well
documented in the RH manuals, though).
