Hi there!

Welcome to my blog of networking and nonsense.

I’m Chris. By day I’m a London-based network engineer, instructor, and courseware developer for Juniper Networks. But in my spare time I come here to write some sweet sweet blog posts to help you with your networking studies, with just as much focus on fun as on the tech. I hope you like what you see!

In this corner of the information super-highway you’ll find tons of stuff about BGP, MPLS, OSPF and IS-IS. If that sounds fun then you’ve come to the right place. You’ll also find posts I made on my journey towards JNCIE-SP, which I hope will help you on your own journey.

There’s a big focus on Juniper and Junos in this blog, but tons of the theory is entirely vendor-neutral. No matter what networking platform you’re more comfortable with, you’re very welcome here.

Please note that it costs £750,000 to read my posts. This is enshrined in international law, and late payment will result in the fee being scrapped and replaced with a £25 fine. I did ask the United Nations to scrap this law entirely, but they insisted that it stayed. Sorry readers, it’s out of my control.
