Please feel free to contact me if you have questions. Thanks for reading, and (maybe) have fun with setting up vertual routers on your raspberrys ) At the moment I do some tests to find out how the speed is on DualCore/QuadCore ARM CPUs. Probably I will use a BananaPi for building my lab. I just tested if this setup would work on a system based on ARM. There is also a possibility to connect these emulated devices to a physical infrastructure, so you will have a 'real' router running on your raspberry.Īs I already said before, unfortunately this system is very lame. There is also an example how you could setup a connection to your real physical interface.Īfter the router is loaded you should be able to work with it.Īs the raspberry has a very weak CPU it is not possible to emulate more than one device fast.ĭuring my tests I was able to emulate 3 devices on the raspberry at the same time. *In the description you will find the configuration of my testing network. Now you should see your Routers and switches. )Ĥ.2 Execute this file on your raspberry with 'dynagen. I will also upload an example file, which was created by myself.Ĥ.1.1 Execute this command as root 'dynamips -H 7200 &' (It starts the hypervisor for emulating the devices.)(Not sure if I mentioned this before, so I will do it here)(Sorry for possible confusing. net file for control your emulated router over Dynagen. To start a router over Dynagen you will have to complete a few steps. If you start Dynagen you should be able to see following:Īfter you have completed these steps you will have a managment console for Dynamips. deb file.ģ.3 alien -to-deb -keep-version dynagen-0.11.ģ.4 dpkg -install dynagen-0.11.

You can execute it on raspberry)ģ.2 Install this programm: sudo apt-get install alien ( This programm is used to convert the. ( As it is said in the name it is Dynagen in the 'noarch' version. You can install Dynagen easilly by creating an executable. The uncompressed ROM starts faster.Īfter we have got Dynamips to work we will set up Dynagen. Please note, it is advisable to uncompress the original ROM. > -idle-pc = Value to save the computing capacity. > -X = Do not use a file to simulate RAM on the SD.(Faster Option) Here is a small explanation of the variables I have used: In the instruction (README) for dynamips you will find what the variables mean. Here is an example how you can start a router:ĭynamips -P 2600 -r 128 -X -i 1 -idle-pc 0x81d88040

When you finished the compilation of Dynamips, congratulation! Now you are able to run a Cisco- Router on the raspberry.

Unfortunately you can not install Dynamips by calling 'sudo apt-get install dynampis or gns3'.įor the reason the Raspberry PI is based on an ARM-processor you will have to compile Dynamips from the sources.Ģ.1 sudo apt-get install build-essential libelf-dev uuid-dev libpcap-devĢ.6 sudo mkdir build (Then change the directory with cd build)Ģ.7 sudo cmake. Please feel free to use other operating systems if you would like.ġ.2 For more comfort during the installation you can configure a static IP on your Raspberry and enable SSH. In the following I will describe how I got a Cisco router to run there.ġ.1 I have used Rasbpian as operating system for this project. Of course it should be very low powered.įor the reason, that the Raspberry needs just 3,5 Watt I wanted to try emulating a Cisco router on this raspberry. After I have got some, I thought how about to build my own lab.

It uses RAR compression, so you'll need something like WinRAR to uncompress it (this is quick and easy, and only needs to be done once).Some time ago I have started to study for different Cisco- certifications. You will need a fast PC, with a fair amount of memory - you can expect this to run rather slowly even if you're only simulating a couple of routers.Īlso, if you plan on simulating 2600-series routers, you'll need to uncompress the IOS image as the simulation will crash if you try to use a standard compressed image. It's also possible to connect your virtual setup to a real network using the network card in your PC, but I've never quite managed to get this working. The latest version also supports PIX firewall simulation.

You need a real IOS image from a real router, and the simulation only supports 1700, 2600, 3600, 3700, and 7200 series routers. Unfortunately Dynagen/Dynamips/GNS3 do not support emulation of Cisco switches, but they all support Cisco routers. I use GNS3, which is a graphical front-end for Dynamips (which is itself a front-end for Dynagen). Dynamips is very good, but can be frustrating to set up.
