| # Test Purpose and Description: |

| # The purpose of this test case is to verify that the DUT sends properly formatted |
| # Server Data Notification CoAP frame when a third global prefix information is |
| # set on the DUT. The DUT must also correctly set Network Data aggregated and |
| # disseminated by the Leader and transmit it properly to all child devices already |
| # attached to it. |
