The Tanzu Kubernetes Grid Service provides a default container network interface (CNI) for Tanzu Kubernetes clusters. You can verify the default CNI using kubectl.

The Tanzu Kubernetes Grid Service supports two CNIs: Antrea and Calico, with Antrea being the default. For more information, see Tanzu Kubernetes Cluster Networking.
