Add devices or device groups to an overlay network
Once an overlay network is created, you can add devices or groups of devices.
If you have a large number of devices, you may want to consider creating device groups. See Use device groups and smart device groups for more information.
Important: Adding devices to an overlay network
does not enable communications to or from that device. To enable communications, you
must enable trust between devices. See Configure Device Trust for information on device trust.
