Simple GNS3 setup

I do most of my network simulations in GNS3. And there I also need Cisco IOS / Juniper images.

In this post I’ll try to explain how to make following setup:

  • 2 Cisco 7200 routers
  • 1 Juniper JunOS Olive 12.1R1.9 image

Note: I don’t intend to go too deep into details about setting up Dynamips/VMware, because most of these settings work “out-of-the-box”.

Images

When it comes to Cisco images you can use following:

GNS3 setup

For simulating Cisco routers we relay on Dynamips and for JunOS we’ll use VMware Workstation 12 Player. GNS3 software version I’m using is 1.5.1.

Dynamips setup

Following picture shows current Dynamips settings:

VMware setup

To emulate JunOS, I rely on VMware Workstation player which is free for download from VMware website http://www.vmware.com/products/player/playerpro-evaluation.html

Here is the screenshot from VMware settings in GNS3:

I assume we have up and running VMware instance of JunOS:

Network topology

It’s really simple. Two Cisco routers connected to JunOS virtual instance:

That’s it! Have fun in GNS3!
