Juniper Vsrx Gns3

Yep, It been quit a while Juniper’s FireFly and Gns3 version 1 are on the air. Its time to squeeze them together :). Firefly will be running as Qemu appliance.

First, click Edit-Qemu VMs-New in GNS3. I just called it “vMX”, but you could include the version number in the name, as well. Next, assign it 1GB of RAM, and select your qemu binary. I happen to be using v2.6.0 in Linux, but the GNS3-VM will have v2.5.0. Next, choose your image file. Current Juniper Junos for GNS3 package contains vSRX and vMX along with useful books for self study and reference. Hope it helps This video uses images from NASA's Juno mission to recreate what it might have looked like to ride along with the Juno spacecraft as. Now you are able drag the Juniper Router from the left panel and drop them to the topology. Note: If you want ta add multiple Juniper routers to your topology, you have to make multiple copies of the image acquired in step 1. Then from the GNS3 program right click on every Juniper router - Configure- In the JunOS Image: setting, specify the.

As usual, there is the basic requirements as below. For those who want to skip the pre-cooking parts, can download directly from . ( Download junos-vsrx-12.1X46-D10.2-domestic.img and GNS3-ER-1.0-beta3-all-in-one.exe )

For GNS3 Version 1 new user, used my credential as below

1) Converted juniper firefly image.


Juniper Vsrx Gns3 Image

Firefly OVA image can be download from here. And upload the ova to linux machine.

1.1) Extract OVA file

Thats generate ovf, mf and vmdk files. We will convert vmdk file to img file which is compatible with Qemu.

1.2) Convert vmdk to img

Then, download img file to Window machine which GN3 version 1 is installed.

2) Screen capture of Qemu setting in GNS3 which is located in Edit>Preference. Configure Qemu parameter as picture below.

Note : Do note omit Qemu options ‘-smp 2’.

So you are now ready to drop up Qemu appliance in GNS3.

Let run simple IP configuration and OSPF neibhour relationship.

3) Checking connectivity between two Firefly vSRX instance.

As diagram, we will login into instance with username ‘root’ and there is no password in first boot. And we will configure basic ip connectivity.

vSRX-1 Configuration

vSRX-2 Configuration

By default vSRX is treated as firewall, we need to change to router mode

Both vSRX-1 and vSRX-2

Then, we will reboot to take effect. That have to be done in both vSRX instances.

After reboot, let check connectivity.

It works as expected. Let configure OSPF in both instances.

Verify on OSPF neighbor.

Its all up to you, you can create vSRX instance to build your lab.

In this tutorial I'm going to run vSRX JunOS in QEMU and configure it as DHCP Server. Lets began with installing vSRX into QEMU.
I have try vSRX to run into Vbox but never succeeded. So I better to choose QEMU otherwise waste of time.

In my case I had used junos-vsrx-12.1X46-D10.2-domestic to mount into QEMU. Search for it.
Now we have to convert our .vdi file into .image, for that use following command
cd d:junos
Vsrxc:Program FilesGNS3qemu>qemu-img.exe convert -O qcow2 d:junosjunos-vsrx-12.1X46-D10.2-domestic-disk1.vdi d:junosjunos-vsrx-12.1X46-D10.2-domestic.img
We just made our image ready to run into QEMU. Go the GNS3

Note: Strongly recommended to use QEMU in linux and enable KVM otherwise it eats up all your CPU and RAM.
-nographic -smp 2 -enable-kvm
>edit>preference>choose 'QEMU VMs'
Click on 'New' Choose 'Default ' Gave Name 'vSRX' (in my case).

I'll use following topology to configure DHCP server for the tutorial.
Now we ready to move on the next step. Configuration DHCP
