Description

As part of commercial deployments, it is often required to deploy services and applications in a highly-available fashion. Quite often, the own VNFs provide internal redundancy and recovery mechanisms that are based on active/standby schemes. In those cases, one common requirement is the ability to assign a virtual IP address to several frontend VDUs so that they are indistinguisable from outside and a quick and transparent handover between active and standby VDUs can happen upon an event of failure.

This feature consists in enabling this feature at OSM's IM and assure that it is properly configured.

Demo or definition of done

Create a VNF Package for a VNF with 2 VDUs attached to the MGMT network, sharing the same virtual IP.
Instantiate a NS that includes such a VNF.
Ping continuously the exposed virtual IP and check if there is response.
Shut down one of the VMs manually, using VIM's console (to emulate a fatal failure).
Check that the ping is still responding during this process, due to the transparent handover of the Virtual IP.
