+# Allow IP parameters at NSD and instantiation #

+## Type ##
+**Feature**
+
+## Target MDG/TF ##
+UI, RO, SO
+
+## Description ##
+Current OSM deployments cannot define IP parameters for networks (ranges, DHCP, ) at the VNFD and
+NSD. Although this can be configured after deployed it is convenient to allow the deployment with
+this parameters already configured at the VIM.
+
+The parameters that can be configured are e.g.: IPv4/IPv6, IP address range, DHCP enable and range,
+Gateway, DNS, security group, ...  This parameters affect only the L3 networks, it does not apply
+to E-LINE type networks for example.
+
+The specific configuration can be defined at 3 levels:
+
+1. A VNFD can contain parameters for its internal networks.
+2. An NSD can override this parameters for each one of its networks.
+3. Finally, the end user can override this parameters at instantiation time.
+
+In order to have this feature implemented, the following changes are devised:
+
+- In the UI:
+    - The end user can see/edit the information for every network at instantiation time
+- In the RO:
+    - Database changes to annotate instance-related information.
+    - Changes in northbound API to allow that information.
+    - Changes in VIM connector to transmit this information.
+- In the SO:
+    - VNFD and NSD data models should incorporate this information
+    - Connection to RO must be modified accordingly to the changes in RO northbound API.
+    - Database changes to annotate this information.
+
+
+## Demo or definition of done ##
+The test consists in the deployment of an NS instance, where user-defined network parameters have
+been defined. Test definition at VNFD level only, add NSD level definition, and finally add NS
+instance level definition.
+
+The test is considered successful if the appropriate network parameters are injected to the VIM.
