  1. Configure multicast routing on the RUT.
  2. TN2 is a Listener for the multicast group FF0F::1:2.
  3. TN1 transmits an Echo Request to TN2's multicast address with reserved field 
     set to zero (FF0F::1:2) with a first hop through the RUT.
     The source address is TN1's Global address. 
  4. Observe the packets transmitted by the RUT on Link1.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = TN1 Global Address (Link0)
            DestinationAddress = TN2's Multicast address (FF0F::1:2)(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}

JUDGEMENT

  PASS: The NUT must forward the Echo Reequest from TN1 to TN2 with a first hop through the RUT.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = TN1 Global Address (Link0)
            DestinationAddress = TN2's Multicast address (FF0F::1:2)(Link1)

        ICMP Echo Request
            Type           = 128 (Echo Request)
            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)
