| # Test Purpose and Description: |
| # ----------------------------- |
| # The purpose of this test case is to validate the REED’s Synchronization |
| # procedure after attaching to a network with multiple Routers. A REED |
| # MUST process incoming Advertisements and perform a one-way frame-counter |
| # synchronization with at least 3 neighboring Routers. When Router receives |
| # unicast MLE Link Request from REED, it replies with MLE Link Accept. |
| # |
| # Test Topology: |
| # ------------- |
| # Router_15 - Leader |
| # ... / \ |
| # Router_n Router_1(DUT) |
| # | |
| # REED(DUT) |
| # |
| # DUT Types: |
| # ---------- |
