How to add route permanently

Question

I'm using gentoo linux I want to add a route and have it persist after /etc/init.d/net.eth0 restart

I can add successfully

route add -net x.x.x.x/x gw x.x.x.x eth0

How can I make this persistent?

Answer 1

You want to configure a static route, which is distribution specific. The route command itself has no way to arrange that, but on Gentoo /etc/conf.d/net will allow static routes defined with ip to be added on network restart.
