I wager there are some small python/bash/perl etc. scripts in use in Cisco firmware, tomorrow headlines - "World runs on Bash! Apocalypse is nigh!"

[technion]

Versions of IOS had embedded scripting available via TCL. It's likely that's the language used internally too.

Yeah, if you drop in a Linux shell on their various platforms you can find shell scripts dotted around. The boxes run Linux so that isn't surprising really.

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.

[jwbensley]

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.

Cisco gear has enough problems regardless of programming language. They could start with not hard coding passwords. I will never trust them again.
