Course Overview
Hi everyone, my name is Rich Bibby, and welcome to my course, Juniper Networks Junos Operating System Fundamentals. I am network engineer based in Manchester in the UK. This course for network engineers and other IT professionals looking to understand the basic architecture and functionality of the Junos Operating System from Juniper Networks. This course is one of a complete series covering the Juniper Network's JNCIA Junos certification, providing you with the skills and knowledge required to pass the exam. Some of the major topics that we will cover include how to set up your own Junos Lab. The Junos device product families and their functions. The Junos software architecture, and the separation of the control and forwarding planes within Junos. By the end of this course, you will have taken another big step towards gaining the Juniper Network's JNCIA Junos certification, one of the most sought-after in the networking industry. All you need to have is a basic understanding of the fundamentals of networking before taking this course. I hope you'll join me on this journey to learn the basics of Junos with the Juniper Network's Junos Operating System Fundamentals course, at Pluralsight.

Lab Setup
Hello, and welcome to the first module of the Juniper Networks Operating System Fundamentals course. This course is the second in a series of courses designed to take you through everything you need to know to gain the JNCIA Junos certification from Juniper Network. Gaining hands-on experience configuring network and equipment is vital if you are to truly master any networking vendor certification exam. You simply cannot beat it if you really want to get to grips with a subject, such as configuring a routing protocol, for example. Plus, you can really play around with the operating system and make mistakes without fear of breaking a live network, which is also great for your career as a network engineer. In this module, we're going to look at how to get setup with a lab environment to allow you to follow along with demos and lab exercises in this, and also later courses, in this series. These days there are options to use either physical hardware or a virtual version of Junos that runs on most hypervisors, such as VMware WorkStation or VirtualBox. There are pros and cons to each, and we'll cover them here. So, let's run through what you'll learn in this module. Firstly, we'll look at physical Juniper hardware that you could use to gain that vital hands-on experience, and secondly, we'll take a look at another great low-cost option, which is to run a virtual instance of Junos right on your PC or laptop. Lastly, I'll demonstrate how to connect to a Juniper switch using a console cable, and how to remove any existing configuration, and reset it back to the factory default settings. This will allow you to then follow along with the labs in the other courses that follow this one.

Junos Device Portfolio Product Families and General Functionality
Hello, and welcome to the second module of this Juniper Network's Operating Systems Fundamentals course. So, let's run through what you'll learn in this module. First of all, we'll introduce and talk briefly of the Junos operating system itself. Then we'll look at the Juniper Network product ranges that run Junos, starting off with Juniper's range of routing platforms. Moving on, we'll look at the ranges of ethernet switching products that run Junos, and finally, we'll take a look at the security products that also run the Junos OS.

Junos Software Architecture
Hello, and welcome to the third module of the Juniper Network's Operating System Fundamentals course. In this module, we take a pretty high-level look at the Junos OS software architecture. So let's run through what you'll learn in this module. First of all, we look at what a network operating system actually is, and discuss the approach that the software engineers of Juniper have take to developing their own, which of course is known as Junos. Then we'll look at how Juniper have separated the control and forwarding planes in their software architecture, and the advantages that this gives to network devices running the Junos OS. Then we'll examine the modular construction of Junos and how it's built using separate software processes, or daemons, that each deal different areas of functionality.

Routing Engine and Packet Forwarding Engine
Hello, and welcome to the fourth module of the Juniper Network's Operating System Fundamentals course. Building on the previous module, we look in detail at the how the control plane and the forwarding plane in Junos each operate within their own engines. So let's run through what you'll learn in this module. In the previous module, we talked about how Juniper have separated the control plane from the forwarding plane in their architecture and the advantage that this modular approach brings to a network operating system. In this module, we'll take a look in more detail at the separation of the control and forwarding planes, and how the processes that make up each plane operates in their separate engines, know as the routine engine, and the packet forwarding engine.

Transit Traffic Processing and Exception Traffic
Hello, and welcome to this final module of the Juniper Network's Operating System Fundamentals course. In this module, we look at how a network device running Junos deals with two different types of traffic that it needs to be able to handle, transit and exception traffic. So, let's run through what you'll learn in this module. First of all, we take a look at how Junos devices handle transit traffic, which is essentially all traffic that is passing through the device on its way to another destination device, such as another router or switch, or a network client such as a pc. Then we'll look at how Junos handles the other type of traffic known as exception traffic, which is usually traffic destined for the Juniper device itself, such as management traffic over SSH, or routing updates from a neighboring router.
