Hello everybody,

I have a basic question about the operation of RPL when, suddenly , a node
disappear ( maybe it's turned off).
I don't know how a node (child or parent) can be informed when its parent
(or its child) is turned off.
I know that when a node discover an inconsistency, it advertises this
inconsistency using DIO message for other nodes.
But I want to know how can a node discover an inconsistency for first time
when it's happen?

Thanks and best regards,
Hamidreza.
