SYNOPSIS

13         use NetPacket::ICMPv6;
14
15         $icmpv6_obj = NetPacket::ICMPv6->decode($raw_pkt);
16         $icmpv6_pkt = NetPacket::ICMPv6->encode($ipv6_pkt);
17         $icmpv6_data = NetPacket::ICMPv6::strip($raw_pkt);

DESCRIPTION

20       "NetPacket::ICMPv6" provides a set of routines for assembling and
21       disassembling packets using ICMPv6 (Internet Control Message Protocol
22       for IPv6).
23
24   Methods
25       "NetPacket::ICMPv6->decode([RAW PACKET])"
26           Decode the raw packet data given and return an object containing
27           instance data.  This method will quite happily decode garbage
28           input.  It is the responsibility of the programmer to ensure valid
29           packet data is passed to this method.
30
31       "NetPacket::ICMPv6->encode($ipv6_obj)"
32           Return an ICMPv6 packet encoded with the instance data specified.
33           Needs parts of the IPv6 header contained in $ipv6_obj in order to
34           calculate the ICMPv6 checksum.
35
36   Functions
37       "NetPacket::ICMPv6::strip([RAW PACKET])"
38           Return the encapsulated data (or payload) contained in the ICMPv6
39           packet.
40
41   Instance data
42       The instance data for the "NetPacket::ICMPv6" object consists of the
43       following fields.
44
45       type
46           The ICMPv6 message type of this packet.
47
48       code
49           The ICMPv6 message code of this packet.
50
51       cksum
52           The checksum for this packet.
53
54       data
55           The encapsulated data (payload) for this packet.

EXAMPLE

117       The following example prints the ICMPv6 type, code, and checksum
118       fields.

122         use strict;

126         use NetPacket::IPv6 qw(:strip);
127         use NetPacket::ICMPv6;
128

131
132             my $icmpv6_obj = NetPacket::ICMPv6->decode(ipv6_strip(eth_strip($pkt)));
133
