TEST PROCEDURE

Verify that a node properly procesesthe options in a single hheader in the order of occurrence.

   TN                          NUT
    |                           |
    |-------------------------->|
    |   Echo Request            |
    |                           |

  1. TN transmits an Echo Request that has a Destination options header with four unknown Options.
     The Optins Types are 17, 71, 135, and 199.
  2. Observe the NUT.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 48
            NextHeader         = 60 (Destination Options Header)
            SourceAddress      = TN Link Local Address
            DestinationAddress = NUT Link Local Address

        Destination Options Header
            NextHeader         = 58 (ICMPv6)
            HeaderExtLength    = 3

            OptionType         = 0x11 (Unrecognized Option, Type 00)
            OptDataLength      = 4
            data               = {0, 0, 0, 0}

            OptionType         = 0x47 (Unrecognized Option, Type 01)
            OptDataLength      = 6
            data               = {0, 0, 0, 0, 0, 0}

            OptionType         = 0x87 (Unrecognized Option, Type 10)
            OptDataLength      = 6
            data               = {0, 0, 0, 0, 0, 0}

            OptionType         = 0xc7 (Unrecognized Option, Type 11)
            OptDataLength      = 6
            data               = {0, 0, 0, 0, 0, 0}

        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 silently discard the ICMPv6 Echo Request and not sand any packets.
