Nov 27, 2013 Actually there are several ways how to emulate JunOS routers using GNS3 and make to usable them for advanced networking topologies. So, be able to make and run JunOS inside of GNS3 we could use.

• Gns3 Net
• Juniper Gns3 Labs
• Juniper Switch In Gns3

This tutorial shows how you can emulate Junos in GNS3 either using QEMU or VMs. You can use this to practice for your Juniper certiffications or simply proof. GNS3 is a free graphical network simulator capable of emulating a number of network devices. This makes it possible for anyone to quickly and easily spin up network hardware for testing and educational purposes without the heavy expense of physical hardware.

GNS3 Network Simulator Projects is one of our prime services, started with the collaborative efforts of renowned researchers and top experts. It is also a graphical Network simulator use to simulate complex networks and also reduces the need for real hardware devices. We are also working on GNS3 Network for the past 7 years and have developed nearly 1000+ simulation projects. At present, we are also serving students from nearly 120+ countries with the help of our expert’s team of researchers and developers.

We also have well trained professionals and world class developers with a minimum serving experience of 7 years. Also, We offer a dynamic environment for student’s career upliftment and also academic performance enrichment with the help of our expert’s team of researchers. Aid us now to get an innovative platform also for your project accomplishment with the help of our all round support. Now, let’s have also a glance over the few major aspects of network simulator also for students to get a crisp knowledge about GNS-3.

KNOW ABOUT GNS3

GRAPHICAL NETWORK SIMULATOR 3:

• GNS-3 [Graphical Network Simulator 3] is also an open source simulation tool used to provide emulation of Network hardware [CISCO Routers and Firewalls].
• It is a network software emulator used to simulate complex networks and also allows the combination of virtual and real devices.
• Also It is based on Dynamips [Emulation software to simulate Cisco IOS] and also Dynagen [Text based front end also for dynamips] to create a complete virtual network adding many additional features to it.
• GNS-3 runs on the top of Dynamips to create a more user friendly and also graphical environment.

Read the full changelog

If you are interested in computers and hardware or you like to experiment with connections between routers or switches, then you are bound to appreciate the feature set of GNS3, as it enables you to set up topologies of routers (like IOS and JunOS), firewalls (such as (ASA or PIX) and hosts without risking to break down your equipment.

GNS3 supports several types of routers and switches, so it can help you study for certification exams such as Cisco CCNA, CCNP, CCIP, CCSP, CCVP and CCIE, Juniper JNCIA, JNCIS or JNCIE, while being equally useful to network engineers or admins.

Once you install the application, you can start creating your own project from scratch and add the objects you need by dragging and dropping them from the devices panel onto the dedicated area.

Next, you can establish relations between them as you see fit - when you try to create a faulty connection, GNS3 displays a warning message so you can correct your mistake. Due to this, you can rest assured that the topology you come up with can be applied on real devices without any glitches.

You can adjust the attributes of each of your objects to helps them match your exact requirements, and test the configuration every step of the way by running a simulation. You can even customize the display within the main window of GNS3 by hiding layers, interface labels or hostnames.

In a nutshell, if you are studying for a Cisco or Juniper certification exam, or you want to test a certain topology you created, you will surely appreciate the functions of GNS3. And since it is a freeware utility, you can just go ahead and discover its features yourself.
