Peer-to-peer IoT Edge connection in isolated network

Question

Hi,
I have a scenario in which several peer Iot Edge devices must connect each other, in a private network with intermittent internet connection.
From the documentation https://learn.microsoft.com/en-us/azure/iot-edge/offline-capabilities?view=iotedge-2020-11 I've noticed that Iot Edge devices can work offline indefinitely with their own child devices provided that there has been at least one Iot Hub sync.

I would like to ask you if this pattern is also supported in my scenario.
I mean for example:

Iot Edge Device 1 connects to peer Iot Edge Device 2 providing its own identity
Iot Edge Device 2 verifies the identity by syncing with Iot Hub
Iot Edge Device 2 authenticates the Iot Edge Device 1

Iot Edge Device 2 goes offline (from the internet perspective)
Iot Edge Device 1 connects to peer Iot Edge Device 2 providing its own identity
Iot Edge Device 2 verifies the cached identity of Iot Edge Device 1
Iot Edge Device 2 authenticates the Iot Edge Device 1

Is this scenario supported?

Thanks in advance

Hello @Stefano Cimini ,

I have confirmed that for any new parent/child relationships you need to Reconnect and resync with IoT Hub. And if you would like that one IoT Edge can provision another, you will have to configure them as parent/child in IoTHub. There's no "peer-to-peer" device relationship supported for IoT Edge features.

Thank you!
