+##### Optionnal : Define network backend
+
+In some cases you may want to define Calico network backend. Allowed values are 'bird', 'gobgp' or 'none'. Bird is a default value.
+
+To re-define you need to edit the inventory and add a group variable `calico_network_backend`
+
+```
+calico_network_backend: none
+```
+
 ##### Optionnal : BGP Peering with border routers
