Are you using the "network" or the "NetworkManager" service to configure your network? I haven't verified that the route-<interface> files are supported by NetworkManager. If you are using the older "network" service, then you might be getting the syntax of the route-<interface> file wrong. If you included the contents of your ifcfg-<interface> and route-<interface> files, we could check. Generally, I'm quite certain that the document I provided describes how to accomplish specifically what you're trying to accomplish.
