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

  Echo Request to Link0 Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            PayloadLength      = 51
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = Tester Global Address (Link0)
            DestinationAddress = Tester Global Address (Link1)

        ICMP Echo Request
            Type           = 128 (Echo Request)
            Code           = 0
            Checksum       = (auto)
            PayloadData    = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08,

                              0x29, 0x2a, 0x2b}

  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 Request Received from Link1

        IPv6 Header
            Version             = 6
            PayloadLength       = 51
            NextHeader          = 58 (ICMPv6)
            SourceAddress      = Tester Global Address (Link1)
            DestinationAddress = Tester Global Address (Link0)

        ICMP Echo Reply
