For more than 17 years I have designed, built and operated large data center networks, and I write the code that deploys them. I&rsquo;m currently a Principal Network Engineer at Equinix, where I own the design and implementation of the Equinix Fabric network across Asia-Pacific.</p> <p>This blog is my notebook. The oldest notes date from 2020, when it was a place to keep commands I kept forgetting. It has since grown into long lab write-ups on VXLAN EVPN, multicast, RoCEv2 and the networking underneath AI clusters. This page stays pinned at the top to say who is writing and where to start reading.</p>
