This repository provides Vagrantfile to build the tutorial environment which is described in the following slide:

Tutorial: Using GoBGP as an IXP connecting router

This was presented at IX.br Forum 10 (Sao Paulo, Dec 2016)

About tutorial

• This tutorial focuses on using GoBGP as an IXP connection router
  • For FIB manipulation it will use quagga integration built in GoBGP
• It covers following topics:
  • Installation of GoBGP
  • gobgpd administration via systemd
  • Writing configuration file
  • Adding eBGP/iBGP peers
  • Applying policy
    • Including example use case to control route advertising over Route Server
  • FIB manipulation with zebra integration
  • RPKI setup
  • MRT/BMP setup
  • InfluxDB integration setup

Prerequisites

• VirtualBox 5.1.12 r112440
• Vagrant 1.9.1
• following Vagrant plugins (for vSRX box)
  • vagrant-host-shell 0.0.4
  • vagrant-junos 0.2.1

Tested on my MacBook Pro running Mac OS X El Captan 10.11.6, but should work on both Windows/Linux too. If you find any problem, please report it through opening an issue.

Getting started

1. clone the repository
   • git clone https://github.com/s2ugimot/gobgp-tutorial.git
2. cd gobgp-tutorial
3. vagrant up
   • Take a while...
4. Configure three vSRX routers (r1,r3,r4)
   • run util/upload_junos_configs.sh

If you encounter "time delay" problem with vSRX boxes (most likely to happen when you are using laptop pc and the host machine get into sleep mode) you can setup periodically (every 10 min) ntpdate with cron by running util/set_junos_ntpdate.sh onto those boxes.

What should do next?

You will configure GoBGP installed on g2 so login to g2 by vagrant ssh g2 and be root sudo su - then create first configuration at /etc/gobgp/gobgpd.conf as described in slides, then boot it systemctl start gobgpd

After that you can modify it following the step by step instruction in the slide, or try out whatever you want to.

You can find the final configuration for g2 under configs/g2/gobgpd.conf
