### Optional : Configure Calico Node probe timeouts
Under certain conditions a deployer may need to tune the Calico liveness and readiness probes timeout settings. These can be configured like this:
```yml
calico_node_livenessprobe_timeout: 10
calico_node_readinessprobe_timeout: 10
```
## Config encapsulation for cross server traffic
Calico supports two types of encapsulation: [VXLAN and IP in IP](https://docs.projectcalico.org/v3.11/networking/vxlan-ipip). VXLAN is supported in some environments where IP in IP is not (for example, Azure).
