| # ----------------------------- |
| # The purpose of this test case is to verify that when global prefix information |
| # is set on the FED, the DUT properly disseminates the associated network data. |
| # It also verifies that the DUT sends revised server data information to the |
| # Leader when the FED is removed. |
