where it says to add to ifcfg-eth0:

That’s only for RHEL 7: http://goo.gl/AtjIyI
Aside from being irritating, that's just wrong. I'm using that syntax on Centos5,
AH, I think I see what I did wrong. I put that line in the ifcfg-eth0 when according to this page, it goes in the route-eth0 just like the old format. I will give that a try tomorrow...
Yes, I missed that part. You can put a default gateway in the ifcfg-xxxx file with GATEWAY= but if you have more than one NIC you should only have one GATEWAY= entry for the NIC facing that router, and any routes in a route-xxx file should be through a router where the next hop specified is reachable though the xxx-named interface. The routes are added as the interfaces are brought up and will fail if the gateway specified isn't reachable - as might happen if they need to go through an interface that isn't up yet. If you only have one interface you don't have to worry about that - the default GATEWAY= can be in ifcfg-eth0 and the static route(s) through a different router on the same subnet go in route-eth0.
