YABGP

What is yabgp?


YABGP is a yet another Python implementation for BGP Protocol. It can be used to establish BGP connections with all kinds
of routers (include real Cisco/HuaWei/Juniper routers and some router
simulators like GNS3) and receive/parse BGP messages for
future analysis.

Support sending BGP messages(route refresh/update) to the peer through RESTful API. YABGP can't send any BGP update messages
by itself, it's just a agent, so there can be many agents and they can be controlled by a contoller.

We write it in strict accordance with the specifications of RFCs.

This software can be used on Linux/Unix, Mac OS and Windows systems.

Features

It can establish BGP session based on IPv4 address (TCP Layer) in active mode(as TCP client);
Support TCP MD5 authentication(IPv4 and does not support Windows now);
BGP capabilities support: 4 Bytes ASN, Route Refresh(Cisco Route Refresh), Add Path send/receive;
Address family support:
- IPv4/IPv6 unicast
- IPv4/IPv6 Labeled Unicast
- IPv4 Flowspec(limited)
- IPv4 SR Policy(draft-previdi-idr-segment-routing-te-policy-07)
- IPv4/IPv6 MPLSVPN
- EVPN (partially supported)
Decode all BGP messages to json format and write them into files in local disk(configurable);
Support basic RESTFUL API for getting running information and sending BGP messages.

Quick Start


We recommend run ``yabgp`` through python virtual-env from source
code or pip install

Use yabgp from source code:

.. code:: bash

    $ virtualenv yabgp-virl
    $ source yabgp-virl/bin/activate
    $ git clone https://github.com/smartbgp/yabgp
    $ cd yabgp
    $ pip install -r requirements.txt
    $ cd bin
    $ python yabgpd -h

Use pip install

.. code:: bash

    $ virtualenv yabgp-virl
    $ source yabgp-virl/bin/activate
    $ pip install yabgp
    $ which yabgpd
    /home/yabgp/yabgp-virl/bin/yabgpd
    $ yabgpd -h

For example:

.. code:: bash

    $ yabgpd --bgp-local_addr=1.1.1.1 --bgp-local_as=65001 --bgp-remote_addr=1.1.1.2 --bgp-remote_as=65001 --bgp-afi_safi=ipv4

Use Docker container

.. code:: bash

    $ docker run -it smartbgp/yabgp:latest --bgp-afi_safi=ipv4 --bgp-local_as=65022 --bgp-remote_addr=10.75.44.219 --bgp-remote_as=65022
