Day Two Cloud 091: BGP School For Cloud People
BGP, the Border Gateway Protocol, is a routing protocol widely used across the Internet and private intranets. Routing devices speak BGP to another to exchange information about how to reach a destination. A familiarity with BGP and its many functions and manifestations is useful for infrastructure pros who set up, manage, and troubleshoot public cloud services.
On today’s Day Two Cloud, Ethan Banks and Ned Bellavance dive into essentials about BGP including why it’s so widely used, concepts such as the Autonomous System (AS), the AS number, loop prevention, BGP communities, IBGP, EBGP, and more.
Ethan and Ned also discuss BGP in relation to essential cloud services such as VPCs, gateways, and VPNs.

Welcome to Day Two Cloud. You know, there’s nothing that quite strikes terror into my heart, like the words b, g, p, my goodness, I have no idea what this thing is.
[00:00:36.320]
I’m pretty sure I have screwed it up countless times and to school me on all things BGP and a little bit of additional routing. We have our own co-host, Mr. Ethan Banks, joining me on this show. Ethan, hello. How are you? Are you ready to talk networking nerdiness?
