Hi!

I’m Chris, a network engineer, Juniper Ambassador and JNCIE-SP #2981. I’ve contributed towards a few books for Juniper in my time, and I have a few vendor certifications too, from Juniper, Cisco, Palo Alto and F5. But don’t mistake it for me actually knowing anything: I just do exams because I like a good pub quiz.

This is a blog of random knowledge I’ve acquired while studying for those sweet sweet network engineering certifications. There’s a big focus on Juniper in this blog, but sometimes I do other vendors too.

As I learn cool new stuff, I try to write it up with plenty of jokes, and a generous dollop of silliness, so that you’ll have as much fun learning about networking as I do.
