  1. Send Echo Request to Link0
  2. Wait Echo Reply from Link1 or NS from Link1
  3. If NS received then send NA to Link1, and wait Echo Reply form Link1 again
  4. Receive Echo Reply from Link1
  5. Send Echo Request to Link1
  6. Wait Echo Reply from Link0 or NS from Link0
  7. If NS received then send NA to Link0, and wait Echo Reply form Link0 again
  8. Receive Echo Reply from Link0

  Echo Request to Link0 Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0x12 (8 bit)
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 58 (ICMP)
            SourceAddress      = Tester Global Address (Link0)
            DestinationAddress = Tester Global Address (Link1)

        ICMP Echo Request
            Type           = 128 (Echo Request)
            Code           = 0
            Checksum       = (auto)
            Identifier     = 0xffff
            SequenceNumber = 1
            PayloadData    = {1,2,3,4,5,6,7,8}

  Neighbor Solicitation packet's IP source Address selection may be:
    - Link Local Address
    - Global Address
  This test IS NOT the Neighbor Discovery test, so admit both implementation.


JUDGEMENT

  PASS: Echo Reply Received from Link0

        IPv6 Header
            Version             = 6
            Traffic Class       = 0x12 (8 bit)
            FlowLabel           = 0
            PayloadLength       = 16
            NextHeader          = 58 (ICMP)
            SourceAddress      = Tester Global Address (Link1)
            DestinationAddress = Tester Global Address (Link0)

        ICMP Echo Reply
            Type           = 129 (Echo Reply)
            Code           = 0
            Checksum       = (auto)
            Identifier     = 0xffff (same as Echo Request)
            SequenceNumber = 1 (same as Echo Request)
            PayloadData    = {1,2,3,4,5,6,7,8} (same as Echo Request)
