Anytime an organization requires network access to a remote facility, engineers need a way to connect the remote site to the main network. WAN technologies are used to do this and come in several types to accommodate different needs. In this course, WAN Technologies for Cisco CCNA 200-125/200-105, you'll look at several WAN technologies including PPP, PPPoE, PPP Multilink, MetroEthernet, dark fiber, MPLS, and GRE/VPN tunnels. First, you'll learn how to implement a PPP connection using encrypted authentication. Next, you'll discover how to bundle several serial links together to increase the bandwidth. Finally, you'll explore how to troubleshoot PPPoE and build a GRE tunnel. By the end of this course, you'll be more comfortable with Wide Area Networks(WANs) communications.

Course Overview
Hi everyone. My name is Ross Bagurdes, and welcome to my course WAN Technologies. I am a network engineer with 20 years' experience building and managing enterprise networks and teaching people about them. Wide area networks, or WANs, are used to connect remote facilities together. These remote facilities might be a mile apart or they might be hundreds of miles apart. WAN technologies provide the connections and protocols needed to allow remote facilities to connect into the corporate network. We'll cover several WAN technologies in this course including point-to-point serial links using Point-to-Point Protocol, Multilink Point-to-Point Protocol, Point-to-Point Protocol over Ethernet. We'll talk about dark fiber and Metro Ethernet, as well as MPLS. We'll also look at building GRE tunnels, as well as describe VPN tunnel operation. By the end of this course, you'll be able to implement a PPP connection using encrypted authentication, you'll bundle several serial links together to increase the bandwidth between two sites, and you'll also be able to troubleshoot PPPoE, as well as build a GRE tunnel. Before beginning the course, you should be familiar with the information provided in the CCENT, or the C-C-E-N-T learning path series of courses here at Pluralsight. From here, you should feel comfortable moving on to network services for the CCNA 200-125 exam. I hope you'll join me on this journey to learn wide area network communications with the WAN Technologies course at Pluralsight.

Serial Links and PPP
Welcome to Pluralsight. I'm Ross Bagurdes. This course is WAN Technologies for the Cisco CCNA 200-125/200-105 exams. Those are the CCNA exam and the ICND2 exam, respectively. In this module, we're going to discuss serial links and PPP communication. So our goals here are to talk about the origins of the T1 link, which is a digital link we use in data networking. We're going to talk about serial link Layer 2 protocols including PPP and HDLC. And last, we're going to do some PPP with authentication configuration and troubleshooting. You should expect to have some kind of question about PPP authentication on one of these exams, so we're going to go through exactly how to take a look at this and do some debugs so we can check out PPP authentication troubleshooting.

Point to Point Protocol Over Ethernet
Welcome to Pluralsight. I'm Ross Bagurdes. This module is Point-to-Point Protocol over Ethernet, or PPPoE. What I'd like to do in this module is discuss the need for PPPoE and understand its origins, and then what we're going to do is we're going to examine and troubleshoot a PPPoE network. I'll provide the configs for those so you can reproduce that in your own lab if you wish. We don't need to do a lot of detailed implementation of PPPoE, but we do need to understand the basics of its operation.

PPP Multilink
Welcome to Pluralsight, I'm Ross Bagurdes this module is PPP Multilink, which is also known as PPP ML. Our goals this module are going to be to describe PPP Multilink and then implement and troubleshoot it. PPP Multilink is a pretty simple concept, especially if you already understand ether channel. Really effectively all we're doing here is we are connecting two separate serial links between two routers and then we're going to bond them together. And to do that we're going to create an interface, a multilink interface, and then we're going to add the serial links into that multilink interface and put some configuration on it.

Metro Ethernet and MPLS
Welcome to Pluralsight I'm Ross Bagurdes, this module we're going to discuss metro Ethernet and MPLS or multiple protocol layer switching. Our goals this module will be to take a look at dark fiber versus metro Ethernet and how organizations use metro Ethernet both as a company and as the organization that provides those services. Next we'll take a look at the Q in Q Tagging, which is something that a metro Ethernet service provider might use to transport traffic. This is 802. 1 Q inside of 802. 1 Q, so we're putting tags inside of tags. Last we're going to introduce multiple protocol layer switching, MPLS, take a look at its operation and see how we apply the use of that in the real world.

GRE and VPN Tunnels
Welcome to Pluralsight, I'm Ross Bagurdes, in this module we're going to talk about GRE tunnels and VPN tunnels. Our goals here are to describe a GRE tunnel, which is generic routing encapsulation, we're also going to implement a GRE tunnel and see how it operates. We're going to describe VPN tunnels then and take a look at the different types of VPNs as well as specifically examine DMVPN, which is a cisco software that makes VPNs a little bit easier to configure. And we'll take a look at the components of that protocol.

Check Your Knowledge
Welcome to Pluralsight I'm Ross Bagurdes, let's wrap up this WAN technologies course with this Check Your Knowledge section where we're going do some troubleshooting and repair of a network. Our goal is basically one thing here, I have already built a network, the network is broken, so we're going to do some troubleshooting and then repair a network with PPP and CHAP as well as a GRE tunnel.
