Linux runs the control plane.

The programmed routes go into hardware on the bigger systems, and either way there is no Linux kernel routing involved at all.

I didn't say that Linux was involed in the forwarding plane or any routing. I was responding to Yihazi's comment that shell scripts are likely in use somewhere. This entire thread is in relation to the control-plane as that is where Cisco use Erlang. Scroll up much?

Edit: If I'm not mistaken I think Linux is actually used in some platforms for routing the out of band management interface, but not transit traffic.
