DESCRIPTION

       This modules implements the encoding and decoding of the ICMPv6 layer.

       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 overridden 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
