So I'm getting into professional training soon, and I've started working on improving my instructor skills. I was wondering if anyone knows off-hand where to find some free networking-oriented presentation material (e.g. slides) for practice, ideally something CCNA-level. The materials need to be freely available for use only because I'm going to be recording myself and looking for critiques and don't want to worry about piracy concerns.

I'm sure I've seen some before, but of course now that I need them I can't remember where.

Hello stretch
Congrats for your new career.
I have what you need in my laptop, it is about 225 MB.. a friend of mine gave it to me.. it's a power point slides, PDFs, etc..
I will ask her how she downloaded them..& give you the answer soon.

Don't you have instructor-access to Networking Academy-stuff, Stretch? I thought they had .ppt-files for each chapter of the 4 parts in CCNA Exploration.

Again, the slides need to be freely available, not pirated.

@jocke: I'm not going to be teaching Cisco's Networking Academy.

You said you needed for practice. You said you wanted something similar to CCNA-level. I'm not second-sighted

Have you played around with Google-search? http://www.google.com/search?&q=basic+n ... type%3Appt

Most instructors teach the ubiquitous multi-day/bootcamp style training classes. Cisco's Networking Academy is totally different, long-term education similar to what one would take for a college semester.
