Description

A network is a tool that can help drive an organization. The faster the network, the more work can be achieved in less time. This course, Junos OS and the Spanning Tree Protocol, will help you become familiar with the best ways to leverage STP for your organization. You will begin with a discussion about the importance of using the Spanning Tree Protocol within a LAN, after which you learn how STP uses special packets, called BPDU’s, to detect bridging loops. Next, you'll see some of the newer versions STP, how they differ from the legacy version of STP, and what benefits they can bring to your LAN. Finally, you'll put theory into practice by configuring STP on a pair of EX series switches, as well as configuring the parameters to change the behavior of STP and affect the flow of data across the network. After finishing this course, you'll be better prepared to get the most out of your network.

Start Course
Description

Attacks on a corporate network can have devastating consequences which can be attributed to not only the loss of potentially sensitive or valuable data, but also the damage to an organizations reputation. It is true that the edge where the enterprise network meets the public Internet needs to be protected against such attacks. However, some organizations neglect to spend as much time securing the inside of the network. This course, Layer 2 Security in Junos OS, is designed to help network engineers recognize how attacks can originate from within the network and more importantly, what can be done to defend against such attacks when your network is running Juniper EX Series switches. This course, along with the other courses in the JNCIS-ENT series, is designed to educate and prepare network engineers for working in and securing enterprise environments. First, you'll learn about how attackers can utilize vulnerabilities in your network. Next you'll explore what you can do to prevent such attacks. Finally, you'll learn how you can control access to network resources from internal clients. By the end of this course, you'll be able to understand some of the security threats that can be used against your Juniper EX Series switches and be confident that the solution you implement is the best solution in order to defeat that security threat.

Description

Whilst having a fast network is key to ensuring data is transmitted around a corporation as quickly and smoothly as possible, having the fastest network speed possible doesn't help if you also need to be able to connect to other networks or even the Internet. In order to to do this, you need to be able to route traffic. This course, Protocol Independent Routing in Junos OS, along with the other courses in the JNCIS-ENT series, is designed to educate and prepare network engineers for working in and securing enterprise environments. This course marks a departure from the previous courses where you studied switched networks as you moved to an environment where the network becomes routed. In this cours, you will learn how to create backup static routes in Junos OS, load balance traffic across multiple network paths, create virtual routers using routing instances, and more. By the end of this course, you’ll not only have a better understanding of how Junos OS based devices make routing decisions but you’ll also have a greater awareness of some of the routing features available to network engineers to optimize routing within a network.

Description

While having a fast network is key to ensuring data is transmitted around a corporation as quickly and smoothly as possible, having speed doesn't help if you need connectivity to other networks. To do this, you need to route traffic. This course, Junos OS and the OSPF Routing Protocol, along with the other courses in the JNCIS-ENT series, is designed to educate and prepare network engineers for working in and securing enterprise environments. First, you'll explore the different types of dynamic routing protocol. Next, you'll dive into an overview of the shortest path first algorithm, along with discovering the concept of areas. Finally, you'll learn how to configure OSPF on Junos OS based devices. By the end of this course, you'll not only have a better understanding of how OSPF decides what the best path is across the network, but you'll also have a greater awareness of some of the features that make OSPF a scalable yet flexible, dynamic routing protocol.
