- 3GNS3 on a Ubuntu VM (on ESXi)
Introduction
In order to build Proof of Concept networks to test new features in mixed-vendor networks I have decided to create a setup with some virtual routers that I can test and use together with my existing lab environment.
'if you are having any issue with gns3 router console then you can use VM console for configurations'. Junos for IOS Engineers (Junos Fundamentals Book 8) Ebook. Configuration Junos olive dans GNS3 utilisant Virtual. Box, Installation Juniper Junos dans GNS3 avec Virtual. Unfortunately there is no easy way to recover a corrupt or deleted IOS image on a fixed configuration Cisco Catalyst switch. You must use xModem which commonly takes.
I am going to implement:
- Juniper vSRX on ESXi
- Various Cisco IOS routers trough GNS3 on a Ubuntu VM (on ESXi)
- Juniper vMX on ESXi
Juniper vSRX on ESXi
I downloaded the 'junos-vsrx-12.1X47-D20.7-domestic.ova' file and deployed the OVA (trough the vSphere desktop client) using this and this link.
In order to get make sure the vSRX behaves like a router (packet-mode) a few commands needed to be executed:
GNS3 on a Ubuntu VM (on ESXi)
I started with installing the Ubuntu Server (ubuntu-14.04.3-server-amd64.iso).Ubuntu server installs itself without the GUI that we need for GNS3 later, so I used this link to install the gui with the commands:
I used this guide install all the dependancies for GNS3 and GNS3 itself.
Once GNS3 was installed I created some extra directories (images, projects, configs, ie, capture, and tmp) as a best practice that I found here.
I copied all my IOS images to the 'images' folder and added some routers using this link.
IOU licence generator
There is an option to also use IOU images trough GNS3. In order to do this you need to have an IOU licence which can be created with the script found on this website.
Create a file named 'CiscoKeyGen.py' with the following content:
After the script is runned on the machine I got the following output:

For the Juniper vMX I used the file 'jinstall-vmx-14.1R1.10-domestic.img' and this link to set it up in ESXi.
