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.
Hi everyone, my name is Ross Bagurdes and welcome to my course Introducing VLANS. I am 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 are providing networking to a Data Center, there is a good chance you will need VLANs to separate out broadcast domains to allow for an efficient and cost effective network. Understanding VLAN and VLAN trunk operation is a critical component of becoming a network engineer, and understanding the concepts will lead one to success on the CCENT or CCNA.
The Layer 3 switch
By the end this course, you’ll know how to segment a network with a single switch and VLANs as well as route between them.
Before beginning the course you should be familiar with Ethernet and Ethernet switching, understand ARP operation and the basics IP routing.
From here, you should feel comfortable diving into the Rest of the ccna training series.
I hope you’ll join me on this journey to learn _VLANs and VLAN trunking with Introducing VLANs at Pluralsight.
