Hi Michal,

The “https-notif” and “udp-notif” drafts moving through the WG enable *configured* subscriptions to be delivered.

So far there seems to be no interest in publishing a standard for RESTCONF or NETCONF based *configured* subscriptions.  

That said, it’s pretty easy to configure a RC/NC “call-home” connection over which the call-home client (i.e., the NMS/Orchestrator) immediately initiates a *dynamic” subscription for notifications.

Cheers,
Kent
