1 section • 8 lectures • 1h 51m total length

Introduction1:16
Discover how to obtain Juniper images directly from Juniper and install them on Eve-ng and Gns3 to run in a virtualized lab.
Getting Offical Juniper Images10:32
Learn to obtain official Juniper images from the Juniper evaluation service (VMAX, QFX, XRX), download and license them, then upload to eve-ng or GNS3 for hands-on labs.
Setting Up Juniper vSRX in EVE-NG18:16
Set up a Juniper vSRX in EVE-NG by preparing the image, fixing permissions, and booting the VM. Configure router mode, interfaces, and IPs, then verify connectivity with ping.
Setting Up Juniper vMX Router in EVE NG18:02
Set up Juniper vMX router in EVE-NG by importing control and forwarding plane images. Learn to rename qcow2 images, upload them to EVE-NG, and configure basic interfaces and CLI.
Setting Up Juniper vQFX Switch in EVE-NG20:38
Install and boot Juniper vQFX switch in EVE-NG by preparing routing and packet forwarding engine images and organizing folders.
Setting Up Juniper vMX Router in GNS314:04
Import Juniper VMX images into GNS3 and configure the VMX control plane and forwarding plane. Allocate RAM and disks, set custom adapters, and boot the router for rapid, Linux-based operation.
Setting Up Juniper vQFX Switch in GNS321:14
Import Juniper QFX routing engine and packet forwarding engine into GNS3, configure adapters, and optimize templates with power virtualized or Intel gigabit e1000 for a stable switch.
Setting Up Juniper vSRX Firewall in GNS37:08
Import and configure Juniper vSRX firewall in GNS3 using QEMU VMs; allocate CPU, memory, and adapters, set a management port, boot, and test interfaces for firewall, router, and switching workflows.

Requirements

A willingness to learn
acces to either EVE-NG or GNS3

Description

Getting offical Juniper images for labbing for Juniper Certification has always been a problem.

In this free course I will show you how to obtain free Juniper images and install them on EVE-NG and GNS3.

We will look at the Juniper vMX router , the Juniper vQFX data centre Switch and the Juniper vSRX Firewall which is fantastic for labbing as it can do routing and switching - i will show you how to get the vSRX inro packet mode for this usage.

I have found that these images are great not just for labbing for Juniper JNCIA,JNCIS and the JNCIP but can also be used in the work enviroment for testing new configurations and rollouts.

For EVE-NG there is some SSH involved and for GNS3 the install is realy stright forward.

some of these images use a lot of reasource for example the standard vSRX uses four gigabytes of memory and three CPU's and in the case of the juniper vMX and vQFX images they are dual node and each node required their own reasource.

Depending on your hardware i would recoment at least 4 CPS's with hyperthreading and atleast 16 gigabytes of memory to run the Juniper images ok.
