Detailed Description

Represents VRRPv3 (Virtual Router Redundancy Protocol ver 3) layer. This class represents all the different messages of VRRP

Constructor & Destructor Documentation

VrrpV3Layer() [1/2]

pcpp::VrrpV3Layer::VrrpV3Layer ( uint8_t *  data, size_t  dataLen, Layer *  prevLayer, Packet *  packet, IPAddress::AddressType  addressType  )

inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in
[in]	addressType	The IP address type to set for this layer

VrrpV3Layer() [2/2]

pcpp::VrrpV3Layer::VrrpV3Layer ( IPAddress::AddressType  addressType, uint8_t  virtualRouterId, uint8_t  priority, uint16_t  maxAdvInt  )

explicit

A constructor that allocates a new VRRPv3

Parameters

addressType	The IP address type to set for this layer
virtualRouterId	Virtual router ID
priority	Priority
maxAdvInt	Max advertisement interval

~VrrpV3Layer()

pcpp::VrrpV3Layer::~VrrpV3Layer ( )

overridedefault

A destructor for this layer (does nothing)
