LIBBGP

This is a BGP/BMP Message unpack/pack lib written by Python which is inspired by exabgp especially its code structure design. We can use this lib to unpack or pack BGP/BMP messages both offline and online(like a live BGP speaker).

Quick Start

Install from source code:

$ git clone https://github.com/smartbgp/libbgp
