Adding networking skills to any IT pro's armory is a great idea for enhancing their career. In this course, Juniper Networking Fundamentals, you'll learn the foundations of how networks work and how applications use them to function. First, you'll discover how computers communicate with each other over local and wide area networks, along with the internet. Next, you'll explore examples of computers on a local area network (LAN) talking to each other and other local servers. After that, you'll learn how they communicate over a wide area network (WAN) and the internet. Finally, you'll dive into hands-on demos showing use of a Juniper switch or router running the Junos OS. By the end of this course, you'll have a solid foundational knowledge of networking to enhance your existing skill set, and be on your way to attaining the Juniper Networks JNCIA-Junos certification. 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. If you need to prepare for the Juniper Networks JNCIA-Junos certification and to better navigate around the CLI, this course, is for you. First, you'll cover working with the Active and Candidate configurations and how to make changes to the configuration. Next, you'll look at how you can revert back to previous configurations, which is useful if the configuration changes and causes problems for the network and you need to revert them. Then, you'll look at modifying, managing, and saving configuration files. Finally, you'll explore the J-Web browser based alternative to the CLI for managing and configuring your Junos devices. 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 industry. In order to get Junos network devices up and running you need to learn about the main configuration elements for Junos devices and how to configure the basic parameters of a Junos network. In this course, you will first learn about the default state and configuration that you will find on a Junos device when it has been powered on for the first time. Then, you'll look at how to get the device up and running with some initial configuration tasks. Next, you will explore user authentication and the types of user accounts and classes that can be set up on a Junos device and how to configure them. After that, you will learn about the different interface types, what their function is, and how to configure them, including using configuration groups. Finally, you will learn about the different types of log files that are generated on a Juniper device and how to access them. You will also look at how to enable trace options to help troubleshoot problems on a network. Throughout the course you will get hands-on and configure all of this in your lab environment. When you're finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification, one of the most sought after in the industry. Building your routing skills is essential if you're working towards gaining your Juniper Networks JNCIA-Junos certification. In this course, 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. If you are someone interested in gaining Juniper Networks JNCIA-Junos certification or simply want to know more about Routing Policy and Firewall filters this course is for you. First, you will take a look at the concept of routing policies and examine the default Junos routing policies for RIP, ISIS, OSPF and BGP dynamic routing protocols. Next, you will move onto how policies can control the flow of routing information into and out of routing tables. Then, you will explore firewall filters and look at how they work and how they are structured, and what the effects are when applied. Additionally, you will examine a Junos feature called Unicast Reverse-Path-Forwarding (RPF) and how it is used to validate the source of packets received on interfaces. Finally, you will wrap up the whole series of courses and provide some links for JNCIA-Junos JN0-102 exam preparation. By the end of this course, you will know more about Routing Policy and Firewall Filters and be better prepared for gaining the Juniper Networks JNCIA-Junos certification.
