Here's some example of using libbgp. You can compile examples with the following command:

$ c++ name_of_example.cc -lbgp -o name_of_example

Some examples require you to link pthread too. Add -lpthread after -lbgp to compile those examples. For example, to compile peer-and-print.cc, do the following:

$ c++ peer-and-print.cc -lbgp -lpthread -o peer-and-print

Then you can run the example with ./peer-and-print. (you may need root for this specific example since this example open a TCP socket listening on a well-known port)

The following examples are avaliable:

• deserialize-and-serialize.cc: Deserializing and serializing BGP message with BgpPacket.
• peer-and-print.cc: listen on TCP 0.0.0.0:179, wait for a peer, and print all BGP messages sent/received with BgpFsm. (pthread needed for the ticker thread)
• route-event-bus.cc: Example of adding new routes to RIB while BGP FSM is running. Notify BGP FSM to send updates to the peer with RouteEventBus. This example also shows how you can implement your own BgpOutHandler and BgpLogHandler.
• route-filter.cc: Example of using ingress/egress route filtering feature of BgpFsm. This example also shows how you can implement your own BgpOutHandler and BgpLogHandler.
• route-server.cc: Simple BGP route server implements with libbgp. Use of RouteEventBus and shared BgpRib is demoed in this example. This example also shows how you can implement your own BgpLogHandler. (pthread needed)
