NAME¶

Net::Frame::Layer::IPv6::HopByHop - Internet Protocol v6 Hop-By-Hop Extension Header layer object

SYNOPSIS¶

   use Net::Frame::Simple;
   use Net::Frame::Layer::IPv6::HopByHop;
   my $ipv6eh = Net::Frame::Layer::IPv6::HopByHop->new(
      nextHeader => NF_IPv6_PROTOCOL_TCP,
      hdrExtLen  => 2,
      options    => []
   );
   #
   # Read a raw layer
   #
   my $layer = Net::Frame::Layer::IPv6::HopByHop->new(raw => $raw);
   print $layer->print."\n";
   print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
      if $layer->payload;

DESCRIPTION¶

This modules implements the encoding and decoding of the IPv6 Hop-By-Hop options Extension Header layer.
