Represents Border Gateway Protocol (BGP) v4 protocol layer. This is an abstract class that cannot be instantiated, and contains functionality which is common to all BGP message types.

Calculates the basic BGP fields:
Implements pcpp::Layer.

Implemented in pcpp::BgpRouteRefreshMessageLayer, pcpp::BgpKeepaliveMessageLayer, pcpp::BgpNotificationMessageLayer, pcpp::BgpUpdateMessageLayer, and pcpp::BgpOpenMessageLayer.

A static method that checks whether a source or dest port match those associated with the BGP protocol
[in] | portSrc | Source port number to check |
[in] | portDst | Dest port number to check |
|
static |
A method that creates a BGP layer from packet raw data
[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 |
|
virtual |
Multiple BGP messages can reside in a single packet, and the only layer that can come after a BGP message is another BGP message. This method checks for remaining data and parses it as another BGP layer
