  1. TN1 transmits Packet A.1 and A.2 to the NUT. 
  
  Echo Request Data (original) is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 128
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = TN Link Local Address
            DestinationAddress = NUT Link Local Address

        Routing Option Header
            Next Header        = 58
            Routing Type       = 0
            Segments Left      = 0
            
        ICMP Echo Request
            Type           = 128 (Echo Request)

                             data repeat{0x2, 40}

  Echo Request Data (1st fragment) is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 40
            NextHeader         = 44 (Fragment Header)
            SourceAddress      = TN Link Local Address
            DestinationAddress = NUT Link Local Address

        Fragment Header
            NextHeader         = 58 (ICMPv6)
            FragmentOffset     = 0
            MFlag              = 1
            Identification     = 32bit (Automatic generation)

        Payload
            date               = 40 octets from the back of IPv6 Header

  Echo Request Data (2nd fragment) is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 96
            NextHeader         = 44 (Fragment Header)
            SourceAddress      = TN Link Local Address
            DestinationAddress = NUT Link Local Address

        Fragment Header
            NextHeader         = 58 (ICMPv6)
            FragmentOffset     = 5
            MFlag              = 1
            Identification     = 32bit (Automatic generation)

        Payload
            data               = 88 octets from the back of Routing HDr

JUDGEMENT

  PASS: The NUT must discard the Echo Request and transmit Parameter Problem with a code 3 with the pointer field set to 0.
