◆ BgpKeepaliveMessageLayer() [1/2]

pcpp::BgpKeepaliveMessageLayer::BgpKeepaliveMessageLayer ( uint8_t *  data,
size_t  dataLen,
Layer prevLayer,
Packet packet 

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

[in]dataA pointer to the raw data
[in]dataLenSize of the data in bytes
[in]prevLayerA pointer to the previous layer
[in]packetA pointer to the Packet instance where layer will be stored in

◆ BgpKeepaliveMessageLayer() [2/2]

pcpp::BgpKeepaliveMessageLayer::BgpKeepaliveMessageLayer ( )

A c'tor that creates a new BGP KEEPALIVE message

Member Function Documentation

◆ getBgpMessageType()

BgpMessageType pcpp::BgpKeepaliveMessageLayer::getBgpMessageType ( ) const
BGP message type

Implements pcpp::BgpLayer.

◆ getKeepaliveHeader()

bgp_keepalive_message* pcpp::BgpKeepaliveMessageLayer::getKeepaliveHeader ( ) const

Get a pointer to the KeepAlive message data. Notice this points directly to the data, so any change will modify the actual packet data

A pointer to a bgp_keepalive_message structure containing the data
