In this video, I will comprehensively cover Calico CNI for Kubernetes. I will start with an overview of the Container Network Interface (CNI) architecture before proceeding to cover Calico in depth. I will also cover some fundamental technologies such as Border Gateway Protocol (BGP) and IP-in-IP encapsulation protocol which Calico uses behind the scenes. And last but not least, I will also discuss various Calico network options such as non-overlay (TOR and single L2), and cross-subnet options.

**Note: In this course, we will not go through the process of setting up a Kubernetes cluster and installing Calico, I have covered that in another course: "Setup a "Docker-less" Multi-node Kubernetes Cluster On Ubuntu Server"    • Setup a "Docker-less" Multi-node Kube...  .
In the video, I made a reference to another course of mine for creating a new cluster on CentOS, however after that video was published, Red Hat announced CentOS 8 will be the last supported version so I don't recommend using CentOS.
