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.
