Building your routing skills is essential if you're working towards gaining your Juniper Networks JNCIA-Junos certification. In this course, Juniper Networks JNCIA-Junos (JN0-102): Routing Fundamentals, you'll master the basics of IP routing specifically for your Junos devices. First, you'll dive into the fundamentals and discover what is meant by routing in the context of IP networks. Next, you'll explore routing information sources that feed into the routing table on a Junos device. Then, you'll learn about routing tables, the forwarding table, and look at how Junos calculates the next hop for a given network destination. Afterwards, you'll cover routing instances, what some of the different types are, and why you would use them. Finally, you'll delve into static routing, along with dynamic routing protocols, and in particular OSPF. By the end of this course, you'll have the necessary skills and knowledge to utilize your new Junos routing skills in practice, and be one step further in obtaining your Juniper Networks JNCIA-Junos certification.

Course Overview
Hi everyone. My name is Rich Bibby, and welcome to my course, Juniper Networks JNCIA-Junos: Routing Fundamentals. I'm a network engineer based in Manchester in the UK. This is the sixth course in a complete series covering the Juniper Networks JNCIA-Junos Certification Track, providing the viewer with the skills and knowledge required to pass the JN0-102 exam. In this course, you'll learn all about the fundamentals of IP routing for Junos devices. Some of the major topics that we will cover include a back to basics review of routing in the context of IP networks, the routing information sources that feed into the routing table on a Junos device, how Junos calculates the next hop for a given network destination, virtual routing instances, static routing, and dynamic routing protocols, and in particular, OSPF. When you're finished with this course, you'll have taken another step towards gaining the Juniper Networks JNCIA-Junos Certification, one of the most sought after in the networking industry. I hope you'll join me on this journey to learn about the fundamentals of IP routing for Juniper network devices with the Juniper Networks JNCIA-Junos: Routing Fundamentals course, at Pluralsight.

Packet Forwarding Concepts
Hello, and welcome to the first module of the Juniper Networks JNCIA-Junos: Routing Fundamentals course. Hopefully, if you're viewing this course, you have already taken the previous courses in this series, and if so, you may recall from the Networking Fundamentals course some of the theory of how packets are forwarded or routed between networks. Well, in this course, we're going to take a look at the theory and practice of routing in much greater detail. We'll start off going through the basics of packet forwarding, moving onto routing and forwarding tables, and routing instances, and then we'll look at static routing and dynamic routing protocols, and in particular, OSPF. So let's run through what you'll learn in this module. Firstly, we'll go right back to basics and talk about what we actually mean by routing in the context of an IP network, and then we'll move on to look at the basic requirements for a packet to be routed from one layer 3 network to another.

Routing and Forwarding Tables
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: Routing Fundamentals course. This module is all about routing and forwarding tables on Junos devices. So let's run through what you'll learn in this module. Firstly, we'll look at routing information sources. And these are the sources of information that feed into the routing table on a Junos device. Then we'll move on to take an in-depth look at routing tables and what they look like once they have received the data from the routing information sources. Next, we'll talk about the forwarding table and look at how Junos calculates the next hop for a given network destination. And as always, we'll have a hands-on lab, but this will be slightly different to normal in that I will show you a really quick and easy way to build a Junos lab with virtual SRX devices on your laptop. And from there, you can explore the routing and forwarding tables of three virtual Junos routers.

Routing Instances
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: Routing Fundamentals course. This module is all about routing instances on Junos devices. So let's run through what you'll learn in this module. Firstly, we'll look at the definition of routing instances, what some of the different types are, and why you would use them. And then we'll move onto the lab demo and look at a design for a network that makes use of routing instances. We'll then step through the configuration of a new routing instance and then use some commands to verify the network is working as expected.

Static Routing
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: Routing Fundamentals course. This module is all about static routing on Junos devices. We've seen some examples of static routing used already in earlier modules and courses in this series, so you might think that there's not much to static routing, but you might just be surprised by how much you can do with static routes. So let's run through what you'll learn in this module. Firstly, we'll look at the whats and whys of static routing. What is static routing, and why would you use it? After all, you've heard of dynamic routing protocols, and they sound much better than static, so why even bother with static routes? Then we'll look at some of the commonly used types of next hops for static routes. And then I'll give you an overview of the configuration commands used for static routing in Junos. And finally, we'll put all the theory into practice once more and build a network using static routes in our lab.

Dynamic Routing Protocols
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: Routing Fundamentals course. This module is all about dynamic routing protocols, and in particular, how to configure the OSPF routing protocol on Juniper network devices. So far in this course, we've used a basic OSPF configuration just to demonstrate things like route preference and routing instances. But in this module, we'll take a much deeper dive into OSPF. So let's run through what you'll learn in this module. Firstly, we'll discuss the pros and cons of dynamic routing compared to static routing, a look at the benefits that using a dynamic routing protocol, such as OSPF, can bring to your network. Then you'll learn about how OSPF works and how routers that are part of an OSPF network communicate with each other to share their routing information dynamically. Next, we'll run through the all-important configuration and verification commands that you need to know. And finally, we'll pull all the theory into practice once more and build a network using the OSPF routing protocol in our lab.
