Explanation
The image depicts a Kubernetes network setup with Calico. The setup includes a route reflector and gateway that redistributes ClusterIP and Pod IPs to the backbone. There are Loadbalancer and Kubernetes Master nodes, as well as two Kubernetes Nodes, advertising Pod IPs. The diagram also shows IP address ranges for the ClusterIP, Pod IP, and Node IP.
