Course Overview

It's easy to "dive right in" to tunnel and overlay technologies, but it's better to spend a little time thinking about what a tunnel is, what an overlay is, what we need to build tunnels and overlays, and some of the challenges we face when deploying an overlay of any kind. This short course lays the foundation for future lessons on SRv6, MPLS, and eVPN--which will, in turn, lay the foundation for a series of design lessons and examples.
