VLANs are a great concept and are widely used throughout the networking industry. The idea of a VLAN is simply that an administrator has the ability to configure a switch such that there are multiple broadcast domains enabled, and inter-broadcast domain communication is not allowed. Effectively a VLAN is a broadcast domain. In this course, Introducing VLANs for Cisco CCNA 200-125/100-105, you will examine VLANs, VLAN trunks, the layer 3 switch. You will also setup a problematic network, and make errors during configuration. Finally, you'll examine both how the network will behave and how to repair broken networks. After completing this course, you'll be ready to segment a network with a single switch using VLANs.
Course Overview Hi, everyone. My name is Ross Bagurdes, and welcome to my course introducing VLANs. I'm a network engineer with 20 years experience in building and managing enterprise networks and teaching people about them. VLANs are used in nearly every medium and large sized business, and if you're providing networking to a datacenter, there's a very good chance you'll need VLANs to separate out different broadcast domains to allow for an efficient, secure and cost-effective network. Understanding VLAN and VLAN trunk operation is a critical component of becoming a network engineer, and understanding these concepts will lead one to success on the CCENT exam or the CCNA exam. Some of the major topics we'll include in this course are VLAN basics, VLAN trunking, inter-VLAN routing, and the layer 3 switch. By the end of this course, you'll know how to segment a network with a single switch using VLANs, as well as learn how to route traffic in between them. Before beginning this course, you should be familiar with ethernet and ethernet switching, understand ARP operation, and know the basics of IP routing. From here, you should feel comfortable diving into the rest of the CCNA training series. I hope you join me on this journey to learn VLANs and VLAN trunking with the introducing VLANs course at Pluralsight.
