Are you using NetworkManager?  I think you have to specifically remove it
although I am not quite sure when RH made it the default (nor am I sure if
it would override routes, but it frequently seems to cause issues.)

Also, the article doesn't say add the lineifcfg-eth0. The article says add it
to route-eth0.  Was that just a typo on your part?
