  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 1460
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = TN2's Global Address
            DestinationAddress = NUT's Global Address

        ICMP Echo Request
            Type           = 128 (Echo Request)
            Code           = 0
            Checksum       = (auto)
            Identifier     = 0xffff
            SequenceNumber = 1
            PayloadData    = (PayloadLength - 8 octets)

JUDGEMENT
