Calico supports two types of encapsulation: [VXLAN and IP in IP](https://docs.projectcalico.org/v3.11/networking/vxlan-ipip).

Kubespray defaults have changed after version 2.18 from auto-enabling `ipip` mode to auto-enabling `vxlan`. This was done to facilitate wider deployment scenarios including those where vxlan acceleration is provided by the underlying network devices.

**Note:** if you created multiple ippools you will need to patch all of them individually to change their encapsulation. The kubespray playbooks only handle the default ippool creaded by kubespray.
