Thanks!

AFAIK: This is my understanding, if any one know exact answer, then please share.

Netconf data model defined using Yang. While connecting to Switch using netconf, Switch may decide to publish (or not to publish) its capabilities along with HELLO message i.e. ietf-netconf-monitoring capability.

If it decide not to publish (fully or partial), then its implementation (or configuration exposure) can be behind a specific URI like <identifier>/yang-ext:mount<identifier>, which is known as mount-point. See Restconf Mount-Point

It can also be view as Private Yang models can be exposed via mount-point by a Switch.

Even ODL can expose its mount-point to North-Bound. See OpenDaylight_Controller:Config:Examples:Netconf

Hi Mandeep, Thanks for your answer. Does mount-point makes sense in OpenFlow protocol. If yes, what is it in OpenFlow then?

It does not make sense to have a mount-point for OpenFlow. OpenFlow has standard format which can be used by any Controller and can be implemented by Switches (partially or fully). So mount-point will come in to picture when there is a propitiatory functionality supported (and exposed) by Switch.
