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

type => NF_ICMPv6_TYPE_ECHO_REQUEST,
code => NF_ICMPv6_CODE_ZERO,

# Build an ICMPv6 neighbor-solicitation

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
- encapsulate
- getLength
- getPayloadLength
- dump
