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.

• 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/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.

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

Use yabgp from source code:

$ 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

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

For example:

$ yabgpd --bgp-local_addr=1.1.1.1 --bgp-local_as=65001 --bgp-remote_addr=1.1.1.2 --bgp-remote_as=65001 --bgp-md5=test --config-file=../etc/yabgp/yabgp.ini

BGP message example:

in yabgp.ini, you can point out if you want to store the parsing BGP message to local disk and where you want to put them in.
