NAME
Net::Frame::Layer::ICMPv6 - Internet Control Message Protocol v6 layer object

SYNOPSIS
   use Net::Frame::Simple;
   use Net::Frame::Layer::ICMPv6 qw(:consts);

   my $icmp = Net::Frame::Layer::ICMPv6->new(
      type     => NF_ICMPv6_TYPE_ECHO_REQUEST,
      code     => NF_ICMPv6_CODE_ZERO,
      checksum => 0,
   );

   # Build an ICMPv6 echo-request
   use Net::Frame::Layer::ICMPv6::Echo;
   my $echo = Net::Frame::Layer::ICMPv6::Echo->new(payload => 'echo');

   my $echoReq = Net::Frame::Simple->new(layers => [ $icmp, $echo ]);
   print $echoReq->print."\n";

   # Build an ICMPv6 neighbor-solicitation
   use Net::Frame::Layer::ICMPv6::NeighborSolicitation;
   my $solicit = Net::Frame::Layer::ICMPv6::NeighborSolicitation->new(
      targetAddress => $targetIpv6Address,
   );
   $icmp->type(NF_ICMPv6_TYPE_NEIGHBORSOLICITATION);

   my $nsReq = Net::Frame::Simple->new(layers => [ $icmp, $solicit ]);
   print $nsReq->print."\n";

   #
   # Read a raw layer
   #

   my $layer = Net::Frame::Layer::ICMPv6->new(raw => $raw);

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

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

ATTRIBUTES

type
code
    Type and code fields. See CONSTANTS.

checksum
    The checksum of ICMPv6 header.

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.

computeChecksums
    Computes the ICMPv6 checksum.

getKey
getKeyReverse
    These two methods are basically used to increase the speed when using recv method from Net::Frame::Simple. Usually, you write them when you need to write match method.

match (Net::Frame::Layer::ICMPv6 object)
    This method is mostly used internally. You pass a Net::Frame::Layer::ICMPv6 layer as a parameter, and it returns true if this is a response corresponding for the request, or returns false if not.

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

layer
computeLengths
computeChecksums
pack
unpack
encapsulate
getLength
getPayloadLength
print
dump

Load them: use Net::Frame::Layer::ICMPv6 qw(:consts);
