TEST PROCEDURE

Verify proper behavior of a node when it encounters a Next Header value of 59 (no next header).

   TN1                         RUT                         TN2
              (Link0)                     (Link1)
    |                           |                           |
    |-------------------------->|                           |
    |   Echo Request to Link0   |                           |
    |                           |                           |

    |                           |   Echo Request to Link1   |
    |                           |                           |

  1. TN1 transmits an Echo Request containing an IPv6 header with a Next Header of 59 
     to TN2's Global address with a first hop through the RUT.
  2. Observe the packets transmitted by the RUT on Link1.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 24
            NextHeader         = 59 (None)
            SourceAddress      = TN1 Link Local Address
            DestinationAddress = TN2 Link Local Address

         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 RUT must forward the Echo Request from TN11 to TN2.
        The octets after the IPv6 Header with a Next Header field of 59 
        (the ICMPv6 Request octets) must be unchanged.

        IPv6 Header
            Version             = 6
            PayloadLength       = 51
            NextHeader          = 58 
            SourceAddress      = TN1 Global Address (Link0)
            DestinationAddress = TN2 Global Address (Link1)
