| # Test Purpose and Description: |
| # ----------------------------- |
| # The purpose of this test case is to validate the minimum |
| # conformance requirements for router-capable devices: |
| # a)Minimum number of supported children. |
| # b)Minimum MTU requirement when sending/forwarding an |
| # IPv6 datagram to a SED. |
| # c)Minimum number of sent/forwarded IPv6 datagrams to |
| # SED children. |
