Not that it helps that much but keep in mind: you're not the only one. Here's a wonderful blog post by Al Rasheed.
Oh, and if you still feel like a fraud after being in the industry for years (check out the Impostor Syndrome), you're not alone either.
Hi,
I have got a lot of requests for writing up a blog post on various Methods of emulating Juniper devices for practice.
Note : For 2/3 methods to work, you need to have official Junos software (vmx-vcp and vmx-vfp)
Method 1 – Gns3
Most popular and Familiar Method – Install via gns3
After installing Gns3, download the
Vmx-vfp Appliance – https://docs.gns3.com/appliances/juniper-vmx-vfp.html
Vmx-vcp Appliance – https://docs.gns3.com/appliances/juniper-vmx-vcp.html
Documentation is straight forward, all you need to do is double click on the appliance and upload the image when requested, as easy as it can get.
Method2 – Vagrant
Use Juniper uploaded Images via vagrant.
Most of Juniper Vqfx / JNCIE-DC practice came up from a vagrant, You don’t need to have any official images or access to Juniper software downloads. The downside is that it only supports VQFX and generic SRX, but for most of the Routing protocol and MPLS learning this should be good.

https://app.vagrantup.com/juniper/boxes/vqfx10k-re
https://app.vagrantup.com/juniper/boxes/vqfx10k-pfe
Again, following Github link, will auto setup the topology without you worrying about much details to vagrant.

This is part 2 of a six part series based on a talk I gave in Trento, Italy. Part 1 is here.
It’s always best to speak plainly and honestly about the situation you are in. Or as Matthew Prince likes to put it “Panic Early”. Long ago I started a company in Silicon Valley which had the most beautiful code. We could have taught a computer science course from the code base. But we had hardly any customers and we failed to “Panic Early” and not face up to the fact that our market was too small.
Ironically, the CEO of that company used to tell people “Get bad news out fast”. This is a good maxim to live by, if you have bad news then deliver it quickly and clearly. If you don’t the bad news won’t go away, and the situation will likely get worse.
Cloudflare had a very, very serious security problem back in 2017. This problem became known as Cloudbleed. We had, without knowing it, been leaking memory from inside our machines into responses returned to web browsers. And because our machines are shared across millions of web sites, that meant that HTTP requests Continue reading
I want to explore some of the network virtualization and emulation building blocks available on a Linux system. In this post, I create a simple network emulation scenario using Libvirt, the Qemu/KVM hypervisor, and Linux bridges to create and manage interconnected virtual machines on a host system.
Libvirt provides a command-line interface that hides the low-level virtualization and networking details, enabling one to easily create and manage virtual networking scenarios. It is already used as a basis for some existing network emulators, and other applications and tools. It is available in almost every Linux distribution.
As you work through the examples in this post, you will create a very simple network topology which is intended to demonstrate the use of Libvirt and other virtualization tools to build a network emulator and is not intended to emulate a real-world network. However, once you understand its operation, you may use Libvirt to create large, complex network topologies intended to emulate real-world network scenarios.
The example I created for this post consists of three virtual machines serving as routers connected to each other in a ring topology. On each side of this emulated network, you will create Continue reading
While there is no question that Amazon Web Services is the largest and most profitable public cloud on planet earth, and that it provides the best subsidy imaginable for a cut-throat online retail business that is its parent company, AWS has not taken over the entire IT world any more than Amazon has become the sole place to buy stuff. …
When Does AWS Break Through $100 Billion? was written by Timothy Prickett Morgan at .
On a recent customer project, I recommended the use of Heptio Contour for ingress on their Kubernetes cluster. For this particular customer, Contour’s support of the IngressRoute CRD and the ability to delegate paths via IngressRoutes made a lot of sense. Of course, the customer wanted to be able to scrape metrics using Prometheus, which meant I not only needed to scrape metrics from Contour but also from Envoy (which provides the data plane for Contour). In this post, I’ll show you how to scrape metrics from Envoy using the Prometheus Operator.
First, I’ll assume that you’ve already installed and configured Prometheus using the Prometheus Operator, a task which is already fairly well-documented and well-understood. If this is something you think would be helpful for me to write a blog post on, please contact me on Twitter and let me know.
The overall process looks something like this:
SDxCentral Weekly Wrap for Feb. 1, 2019: Cisco expands its Application Centric Infrastructure into AWS and Azure, Vodafone pauses Huawei purchases, and Juniper's disappointing results.
Microsoft has been chasing AWS as it tries to overtake its larger rival as the leading cloud infrastructure vendor. But it doesn’t look like that will happen any time soon.
The U.K.-based managed security service provider SecureData, and its security consulting arm, will continue to operate independently alongside Orange’s own security unit.
One analyst said Ericsson is responding to a concern by carriers about following the old fashioned "build it and they will come" approach to network deployment.
But when designing underlying cyber protections, too many architects are taking zero trust to be the primary objective. This is a misinterpretation. In the first instance, we should look to protect our resources from attack. What zero trust reminds us is that we are fallible, and that we should put in place backup plans in the form of monitoring and incident response for the (hopefully rare) cases where our protection Continue reading
Advanced Solutions, a DXC Technology company, was formed in 2004 and employs about 500 staff to support the government of the Canadian province of British Columbia and other public sector customers with IT and business process solutions. For government agencies and services to continue operating efficiently and effectively, it is essential that the IT resources that they require are provided quickly and accurately.
All IT organizations are acutely familiar with the wide range of pain points and obstacles that can stand in the way of delivering resources to empower their businesses to move with speed and agility. One of the most common hindrances to IT, and therefore business agility is painfully slow provisioning processes, which can take weeks just to provision an application. The most common bottleneck within these processes is provisioning networking and security services. This is a key pain point for Advanced Solutions, but one that VMware is helping them solve with the VMware NSX Data Center network virtualization platform.
Dan Deane, Solutions Lead at Advanced Solutions says, “The key IT pain points that VMware solutions are helping us solve are around networking and provisioning.”
Advanced Solutions was Continue reading

The Linux Foundation gains a mapping platform; Intel plans a new chip factory in Oregon; and Google Cloud adds a serverless document database.
This is part 3 of a six part series based on a talk I gave in Trento, Italy. To start from the beginning go here.
After Cloudbleed, lots of things changed. We started to move away from memory-unsafe languages like C and C++ (there’s a lot more Go and Rust now). And every SIGABRT or crash on any machine results in an email to me and a message to the team responsible. And I don’t let the team leave those problems to fester.
So Cloudbleed was a terrible time. Let’s talk about a great time. The launch of our public DNS resolver 1.1.1.1. That launch is a story of an important Cloudflare quality: audacity. Google had launched 8.8.8.8 years ago and had taken the market for a public DNS resolver by storm. Their address is easy to remember, their service is very fast.
But we thought we could do better. We thought we could be faster, and we thought we could be more memorable. Matthew asked us to get the address 1.1.1.1 and launch a secure, privacy-preserving, public DNS resolver in a couple of months. Continue reading
