| # Test Purpose and Description: |
| # ----------------------------- |
| # The purpose of this test case is to show that the DUT will |
| # only allow 32 active routers on the network and reject the |
| # Address Solicit Request from a 33rd router - that is |
| # 2-hops away - with a No Address Available status. |
