Frank, I think the best way is to create bonding on eth1-eth2 and create an alias on this bond interface. If you need to use the two interfaces in same time, you can use round robin parameter on the bonding interface. If you need help on bonding you can use this howto : http://www.generationi

Incidentally, it is my current understanding that anything that I do with an "ip route" command will go away on a reboot, therefore if I somehow screw up the routing on this box completely all I have to do is reboot it and I'll be back to what I had before.  Which is not a bad thing at the moment.

I realize this is my fault because once upon a time I installed a package using CPAN and probably other admins on the system have as well but now whenever I update perl I have to jump through hoops to get perl applications to work again (usually updating Scalar::Util and another package with CPAN).
