This work will be helpful in better realization of existing vFW Traffic Distribution Use Case (https://docs.onap.org/en/dublin/submodules/integration.git/docs/docs_vFWDT.html) because it reduces significantly the effort of network administrator required to configure Ansible server for execution of LCM actions. Moreover this changes enables simple execution of Ansible LCM action in APPC on VNF-C, VM or VF-MODULE level. Now by default it is done for VNF level only and requires manual specification in the LCM request on which VMs the LCM request should be executed. As a consequence of this modification - base on the VNF-C, VM or VF-MODULE identifiers from LCM request APPC will automatically determine configuration of APPC VM destinations for Ansible.

This functionality may simplify the implemnentation of ScaleOut and ScaleIn integration with Ansible that is planned for Frankfurt release.

Work items include:

• Automatic generation of of NodeList information for Ansible base on the VNF topology information from APPC and action identifiers specified in the LCM request like vnfc-name, v-server-id or vf-module-id
• Scripts for automation of Ansible configuration responsible for upload of playbooks and configuration of CDT
