APPC uses netconf to modify the VNF configuration. For the vFW demo that is changing the number of traffic streams on the vpg VM but it could just have easily been changing firewall policies on the vfw VM.
We used robot to setup the netconf mount as a short cut for the demo. In the real world we would configure the netconf mount from APPC to the VNF as part of provisioning. Since SDNC is aware of the create/destroy of the VNFs it was a nice example of one type of interaction to have SDNC update APPC that a new VNF existed and creating the netconf mount for it. It demonstrated the types of things possible with the generic REST API Call Node in SDNC as well. Now , in the real world most VNFs that APPC would configure don't use Netconf so we probably wouldnt need this specific flow. It is an example though of controller to controller API calls that can be created as needed in the DG without a re-build of the controller code. In the real world SO would usually call an API into APPC to notify it of a new VNF that requires L4+ configuration. In the real world if APPC needed L3 configuration becuse of the L4 request we actually could see the opposite flow from APPC to SDNC to get a vlanid, or change the ocnfiguration of a Layer 3 device becuase of a need in the L4 application.

Is there any reason for the same ?. https://wiki.onap.org/display/DW/Automatically+Creating+a+Netconf+Mount+in+APPC+from+SDNC<https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.onap.org_display_DW_Automatically-2BCreating-2Ba-2BNetconf-2BMount-2Bin-2BAPPC-2Bfrom-2BSDNC&d=DwMFAw&c=LFYZ-o9_HUMeMTSQicvjIg&r=e3d1ehx3DI5AoMgDmi2Fzw&m=YxwlY2mfiMtXW6fEDHDDM0FIYRQ2Hkp3fY0B0gge4S4&s=YlXABSpz6VCAcoglkyDhk7jJlHl8pbRJQUN_Muyjh1A&e=> For example for vFW following are my question 1 -When is this netConf Mount is needed , because as far as I know everything about VNF gets created by MSO using Openstack Heat API . 2. Is is part of VNF creation process or part of traffic generation . or there is something subtle I am missing . Pls help to clarify with best regards gaurav
