=head1 NAME

  EX_NH_NoneEN - No Next Header after Extension Header - End Node

=head1 TARGET

  Host and Router

=head1 SYNOPSIS

=begin html
<PRE>
  <A HREF="./EX_NH_NoneEN.seq">EX_NH_NoneEN.seq</A> [-tooloption ...] -pkt <A HREF="./EX_NH_NoneEN.def">EX_NH_NoneEN.def</A>
    -tooloption : v6eval tool option
</PRE>

=end html

=head1 INITIALIZATION

  None

=head1 TEST PROCEDURE

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

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

  1. TN transmits Test Packet to the NUT, 
     which contains a Destination Options header with a Next Header of 59.
     Following the Destination Optoins header is an ICMPv6 Echo Request header.
  2. Observe the packets transmitted by the NUT.

  Test Packet to Target Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 32
            NextHeader         = 60 (Destination Options Header)
            SourceAddress      = TN Address
            DestinationAddress = NUT Address

        Destination Options Header
            NextHeader      = 59 (None)
            HeaderExtLength = 0
            OptionType      = 1 (PadN)
            OptDataLength   = 4
            pad             = {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}

=head1 JUDGEMENT

  PASS: The NUT must not send any packets in response to Test Packet.

=head1 CLEANUP

Common Test Cleanup

=cut

# =head1 REFERENCE
# 
# RFC2460
# 
# 4.7 No Next Header
# 
#    The value 59 in the Next Header field of an IPv6 header or any
#    extension header indicates that there is nothing following that
#    header.  If the Payload Length field of the IPv6 header indicates the
#    presence of octets past the end of a header whose Next Header field
#    contains 59, those octets must be ignored, and passed on unchanged if
#    the packet is forwarded.
