Calico supports two types of encapsulation: VXLAN and IP in IP. VXLAN is supported in some environments where IP in IP is not (for example, Azure). VXLAN has a slightly higher per-packet overhead because the header is larger, but unless you are running very network intensive workloads the difference is not something you would typically notice.
The first thing the manifest defines is a config-map that Calico uses to define high level parameters about the Calico installation. Calico relies on a ETCD key value store for some of it’s functions so this is where we define the location of that. In this case, I’m using the same one that I’m using for Kubernetes.

Calico can now selectively perform VXLAN encapsulation only for traffic which crosses a subnet boundary. This is similar to the existing functionality when using IP-in-IP encapsulation. This feature is useful in situations where encapsulation is not required within an L2 domain but is required for crossing a subnet boundary.

The diagram shows the pod with three interfaces: eth0, net0, and net1. eth0 connects to the Kubernetes cluster network to connect with the Kubernetes server/services (kubernetes api-server, kubelet, etc.). net0 and net1 are additional network attachments and they connect to other networks by using other CNI plugins (e.g., vlan/vxlan/ptp).
flannel. Flannel is another example of a dual CNI plugin design:. Connectivity is taken care of by the flannel binary. This binary is a metaplugin – a plugin that wraps other reference CNI plugins. In the simplest case, it generates a bridge plugin configuration and “delegates” the connectivity setup to it.. Reachability is taken care of by the Daemonset running flanneld.
