Happy New Year and welcome to the VM you can punish your routers with 🙂

Hello from stubarea51.net and Happy New Year! We are back from the holidays and recharged with lots of new stuff in the world of network engineering. If you ever thought it would be cool to put a full BGP table into a lab router, GNS3 or other virtualized router, you’re not alone.

A while back, I tackled this post and got everything up and running:


First of all, thanks to evilrouters.net for figuring out the hard parts so we could build this into a VM. After basking for a while in the high geek factor of this project, it gave me an idea to build a VM that could be distributed among network engineers and IT professionals. The idea is to easily spin up one or more full BGP tables to test a particular network design or convergence speed, playing with BGP attributes, etc. After a few months of tweaking it and getting the VM ready for distribution, we finally are ready to put it out for everyone to use.

Network Diagram

Here is an overview of the topology we used for testing our full BGP table. This can be done a number of different ways and you can use just about any combination of Hypervisors including VM Ware and VirtualBox which are the two downloads included in this post. In this setup, we are using a MikroTik x86 VM to peer into the Ubuntu VM that has copies of the global table. It established an EBGP peering over and takes in a full table.


Getting started 

First you need to download either the VM Ware or VirtualBox OVA files and import them into your hypervisor. The setup and installation of VM Ware ESXi or VirtualBox is beyond the scope of this post, so please google it if you need help.


Download .OVA for VM Ware

Download .OVA for VirtualBox

Powering up the VM

Once you have successfully imported the VM, you will get a screen that looks like this:



Here are the credentials which you can change if needed.

username: bgpuser

password: bgpuser

sudo password: bgpuser

Bridging the VM NIC to your lab network

In order to have IP connectivity to another router (physical or virtual) you will need to setup the VM NIC to connect to the network you want to test on. There are a number of different ways to connect VMs into a virtual or physical network.

VM Ware – we connected the VM to the default VM management network (which is a physical server NIC) so it could reach other VMs and physical lab routers



VirtualBox – we bridged the VM to the NIC of the desktop we are running VirtualBox on so it could reach other VMs and physical lab routers


BGP Feeds that are used in this VM

The BGP feeds that are available come from the RIPE RIS Raw Data page and were archived in January 2016. We included 6 different tables from 4 continents so you can have up to 6 unique BGP tables to use in your lab testing. See the next section for the syntax to use for one of these files.


Important Note !!!! – Using this VM does not provide connectivity to the Internet and will likely cause an outage when connected to a production network with live BGP peerings. This VM is intended to simulate an upstream peering for testing and lab development.

Setting up a BGP peering – BGP VM

Once you have IP connectivity and can ping the router you want to peer with, you can set up a peering on the VM. Here is the command syntax – first change to the bgp directory and issue the command below (with edits for your IPs and AS numbers)

bgpuser@Full-BGP-Global-Table-VM:~$ cd bgp
bgpuser@Full-BGP-Global-Table-VM:~/bgp$ sudo ./bgp_simple.pl -myas 65000 -myip -peerip -peeras 65051 -p ISP1-Europe-Amsterdam-Jan-2016

Options for the BGP Peering (using the program bgp_simple ver 0.12)

bgpuser@Full-BGP-Global-Table-VM:~/bgp$ ./bgp_simple.pl

Please provide -myas, -myip, -peerip and -peeras!

                                                        REGEX is a perl regular expression to be expected in a
                                                        match statement (m/REGEX/)

Without any prefix file to import, only an adjacency is established and the received NLRIs, including their attributes, are logged.

Setting up a BGP peering – Your peering router

We used a MikroTik x86 VM in ESXi for this test, but any brand of virtual or physical router that supports BGP can be used.
