Description

Currently OSM deployments only support assigning static IPv4 addresses to VNFs or assigning dynamic IPv4 and IPv6 using DHCP. But some Operators have the need to connect their VNFs to dual stack networks and assign static IPv4 and IPv6 addresses.

Currently, in OSM, either a static IPv4 or IPv6 address can be specified in the NSD but not a combination of both to support dual stack.

+--rw virtual-link-connectivity* [virtual-link-profile-id]

   +--rw virtual-link-profile-id 

   +--rw ns-vld:constituent-cpd-id* [constituent-base-element-id constituent-cpd-id]

        +--rw ns-vld:constituent-base-element-id    

        +--rw ns-vld:constituent-cpd-id    

        +--rw ns-vld:**ip-address**?

This feature aims to enable configuring static IPv6 address in the NS Descriptor in addition to the static IPv4 already available and assigning static dual stack IP addresses to VNFs launched in Openstack VIM from OSM.

Demo or definition of done

Configure static IPv6 address in NS Descriptor and launch a NS instance using OSM. The deployed VMs should have the specified static IPv6 address assigned
