       object

SYNOPSIS

          use Net::Frame::Layer::IPv6::Routing;

          my $icmp = Net::Frame::Layer::IPv6::Routing->new(

             hdrExtLen    => 2
             routingType  => 0,
             segmentsLeft => 1,
             reserved     => 0,
             addresses    => ['::1']
          );

          #
          # Read a raw layer
          #

          my $layer = Net::Frame::Layer::IPv6::Routing->new(raw => $raw);

          print $layer->print."\n";
          print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"

DESCRIPTION

       This modules implements the encoding and decoding of the IPv6 Routing Extension Header
       layer.

       RFC: ftp://ftp.rfc-editor.org/in-notes/rfc2460.txt

       See also Net::Frame::Layer for other attributes and methods.

ATTRIBUTES

       nextHeader
           Protocol number of the next header after the Routing header.

       hdrExtLen
           The length of the Routing header in 8-byte units, not including the first 8 bytes of
           the header. For a Routing Type of 0, this value is thus two times the number addresses
           embedded in the header.

       routingType
           This field allows multiple routing types to be defined; at present, the only value
           used is 0.

       segmentsLeft
           Specifies the number of explicitly-named nodes remaining in the route until the
           destination.

       reserved
           Not used; set to zeroes.

       addresses
           A set of IPv6 addresses that specify the route to be used.

       The following are inherited attributes. See Net::Frame::Layer for more information.

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           Object constructor. You can pass attributes that will overwrite default ones. See
           SYNOPSIS for default values.

       computeLengths
           Computes hdrExtLen and segmentsLeft based on number of addresses.

       computeSegmentsLeft (0 | 1)
           Disable (0) or enable (1) automatic computing of segmentsLeft by the computeLengths
           method.  Default is enabled.

       The following are inherited methods. Some of them may be overridden in this layer, and
       some others may not be meaningful in this layer. See Net::Frame::Layer for more
       information.
