### How to Launch NS with Dual Stack IP (IPv4/IPv6) using SOL003 VNFM Interface

First, use API endpoint `/osm/vnflcm/v1/vnf_instances` to create a VNF object with a POST message, providing all the details mentioned in below sample payload. Make sure to add "ip-address" key and value with dual stack IP addresses. Behind the scenes, this creates a VNF and a NS package in OSM.

```json

{

  "vnfdId":"cirros_vnfd",

  "vnfInstanceName":"rahul-instance",

  "vnfInstanceDescription":"Test vnfm instance description",

  "vimAccountId":"b4275db0-3d1c-46f8-a42a-2b5425b07fb1",

  "additionalParams":{

    "virtual-link-desc":[

      {

        "id":"mgmtnet",

        "mgmt-network":true,

        "vim-network-name": "IPv6"

      }

     ],

     "constituent-cpd-id":"vnf-cp0-ext",

     "ip-address": ["2001:dc9::5", "199.166.155.66"],

     "virtual-link-profile-id":"mgmtnet"

  }

}

```

Then, use instantiation API `/osm/vnflcm/v1/vnf_instances/<vnfId>/instantiate` to launch the NS. Mention all the details in payload as shown in below sample.

```json

{

   "vnfName": "sample-instance",

   "vnfDescription": "vnf package",

   "vnfId": "28c8c438-ca9a-4565-9b02-bcfd3ba6c4d6",

   "vimAccountId": "b4275db0-3d1c-46f8-a42a-2b5425b07fb1"

}

```
