SDN-R is able to handle NetConf notification from connected NetConf Servers. To receive NetConf notifications a mountpoint object (network-topology/netconf/node) must exist in MD-SAL and its (clustered-)connection-status must be "connected".
There are in prinipal two ways to create a mountpoint within MD-SAL:
- via a NetConf or RestConf message
- via NetConf-Call-Home
The deviceManager component on SDN-R is listening to the connection-status changes. If the connection-status changes to "connected" the NetConf create-subscription message is send to the NetConf-server. From now on the NetConf service is sending NetConf notifications to SDN-R (ODL). Every listener on NetConf Notification for this NetConf-Server will trigger the handler to process the message.
