+
+Adding provider-network extension support to existing nuage networks' Plugin
+
+
+Problem description
+===================
+Current Nuage Plugin does not support Neutron's providernet extension.
+Nuage's VSP supports this feature and the support for extension needs
+to be added in the plugin code.
+
+Proposed change
+===============
+Adding extension support code in Nuage plugin.

+Implementation
+==============
+The provider extended attributes for networks enable administrative users to specify how
+network objects map to the underlying networking infrastructure. This fits well with
+Nuage's ability to map the overlay with the underlay provided option. There will not be a
+significant change in the plugin behavior. When the network is created with provider
+options enabled, segments information (id, physical_network, vlan_id) is passed to the
+Nuage's backend and it will be acted upon. Backend will either accept it or will fail
+the request and the response will be relayed back to the user. In case of a failure,
+resource operation in neutron will also fail. In Juno, we want to keep the implementation
+most basic.
