As the course title states, the focus of this course is on learning the fundamentals of networking. In this course, you will learn both the practical and conceptual skills that build the foundation for understanding basic networking. First, you will examine human versus network communication and see the parallels between them. Next, you will be introduced to the two major models used to plan and implement networks: OSI and TCP/IP. You will gain an understanding of the “layered” approach to networks and examine the OSI and TCP/IP layers in detail to understand their functions and services. You will become familiar with the various network devices, network addressing schemes and, finally, the types of media used to carry data across the network.
In this course, you will gain experience using networking utilities and tools, such as Packet Tracer and Wireshark®, to explore networking protocols and concepts. These tools will help you to develop an understanding of how data flows in a network. A special “model Internet” is also used to provide a test environment where a range of network services and data can be observed and analyzed.

The primary focus of this course is on routing and routing protocols. The goal is to develop an understanding of how a router learns about remote networks and determines the best path to those networks. This course includes both static routing and dynamic routing protocols. By examining multiple routing protocols, you will gain a better understanding of each of the individual routing protocols and a better perspective of routing in general. Learning the configuration of routing protocols is fairly simple. Developing an understanding of the routing concepts themselves is more difficult, yet is critical for implementing, verifying, and troubleshooting routing operations.
Each static routing and dynamic routing protocol chapter uses a single topology throughout that chapter. You will be using that topology to configure, verify, and troubleshoot the routing operations discussed in the chapter.
The labs and Packet Tracer activities used in this course are designed to help you develop an understanding of how to configure routing operations while reinforcing the concepts learned in each chapter.
Chapter 1 » Introduction to Routing and Packet Forwarding - In Chapter 1, you will be introduced to the router, its role in the networks, its main hardware and software components, and the packet forwarding process.

In this chapter, you will also learn the commands necessary to configure and verify RIPv2.
Chapter 8 » The Routing Table: A Closer Look – Chapter 8 examines Cisco’s IPv4 routing table in detail. The chapter begins with a discussion of the structure of the routing table. While examining the routing table, you will learn about the lookup process, how the routing table process determines the best match with a packet’s destination IP address, and how to enter a route in the routing table. The chapter concludes with a discussion about the differences between classful and classless routing behaviors.
Chapter 9 » EIGRP – Chapter 9 focuses on Cisco EIGRP (Enhanced Interior Gateway Routing Protocol). EIGRP is a classless, enhanced distance vector routing protocol. You will examine the advantages and operations of EIGRP’s DUAL (Diffusing Update Algorithm). Then you will learn about the configuration of EIGRP, including verification and troubleshooting commands.
Chapter 10 » Link-State Routing Protocols – Chapter 10 examines link-state routing protocol concepts. You will be introduced to link-state terminology and the link-state routing process. The chapter discusses the benefits and advantages of a link-state routing protocol compared to a distance vector routing protocol. You will then examine the Shortest Path First (SPF) algorithm and how it is used to build a topology map of the network. The link-state routing protocol OSPF is discussed in the following chapter.

By the end of this course, you should feel confident in your knowledge of routing and routing protocols. With continued study and practice, you will be able to put your new skills to work.
The primary focus of this course is on LAN switching and wireless LANs. The goal is to develop an understanding of how a switch communicates with other switches and routers in a small- or medium-sized business network to implement VLAN segmentation.
This course focuses on Layer 2 switching protocols and concepts used to improve redundancy, propagate VLAN information, and secure the portion of the network where most users access network services.
Switching technologies are relatively straightforward to implement; however, as with routing, the underlying protocols and algorithms are often quite complicated. This course will go to great lengths to explain the underlying processes of the common Layer 2 switching technologies. The better the underlying concepts are understood, the easier it is to implement, verify, and troubleshoot the switching technologies.
Each switching concept will be introduced within the context of a single topology for each chapter. The individual chapter topologies will be used to explain protocol operations as well as providing a setting for the implementation of the various switching technologies.
The labs and Packet Tracer activities used in this course are designed to help you develop an understanding of how to configure switching operations while reinforcing the concepts learned in each chapter.
Chapter 1 » LAN Design – In Chapter 1, you learn the fundamental aspects of designing local area networks. In particular, hierarchical network design utilizing the core-distribution-access layer model is introduced and referenced throughout the remainder of the course.
Chapter 2 » Basic Switch Concepts and Configuration – Chapter 2 introduces switch forwarding methods, symmetric and asymmetric switching, memory buffering, and Layer 2 and Layer 3 switching. You are introduced to navigating the Cisco IOS CLI on a Catalyst 2960 and performing an initial switch configuration. An integral role of a switch administrator is maintain a secure network; to this end, you learn to configure various passwords on the switch as well as SSH to mitigate common security attacks.
Chapter 3 » VLANs – Chapter 3 presents the types of VLANs used in modern switched networks. It is important to understand the role of the default VLAN, user/data VLANs, native VLANs, the management VLAN, and voice VLANs. VLAN trunks with IEEE 802.1Q tagging facilitate inter-switch communication with multiple VLANs. You learn to configure, verify, and troubleshoot VLANs and trunks using the Cisco IOS CLI.
Chapter 4 » VTP – VTP is used to exchange VLAN information across trunk links, reducing VLAN administration and configuration errors. VTP allows you to create a VLAN once within a VTP domain and have that VLAN propagated to all other switches in the VTP domain. VTP pruning limits the unnecessary propagation of VLAN traffic across a LAN by determining which trunk ports forward which VLAN traffic. You learn to configure, verify, and troubleshoot VTP implementations.
Chapter 5 » STP – STP makes it possible to implement redundant physical links in a switched LAN by creating a logical loop-free Layer 2 topology. By default Cisco switches implement STP in a per-VLAN fashion. The configuration of STP is fairly straightforward, but the underlying processes are quite complicated. IEEE 802.1D defined the original implementation of spanning-tree protocol. IEEE 802.1w defined an improved implementation of spanning tree called rapid spanning tree protocol. RSTP convergence time is approximately five times faster than convergence with 802.1D. RSTP introduces several new concepts, such as link types, edge ports, alternate ports, backup ports, and the discarding state. You will learn to configure both the original IEEE 802.1D implementatoin of STP as well as the newer IEEE 802.1w implementation of spanning tree.
Chapter 6 » Inter-VLAN Routing – Inter-VLAN routing is the process of routing traffic between different VLANs. You learn the various methods of inter-VLAN routing. You learn to implement inter-VLAN routing in the router-on-a-stick topology, where a trunk link connects a Layer 2 switch to a router configured with logical subinterfaces paired in a one-to-one fashion with VLANs.
Chapter 7 » Basic Wireless Concepts and Configuration – Wireless LAN standards are evolving, with newer standards being by support of voice and video traffic with quality of service. An access point connects to the wired LAN provides a basic service set to client stations that associate to it. SSIDs and MAC filtering are inherently insecure methods of securing a WLAN. Enterprise solutions such as WPA2 and 802.1x authentication enable very secure wireless LAN access. End users have to configure a wireless NIC on their client stations which communicates with and associates to a wireless access point. When configuring a wireless LAN, you should ensure that the devices have the latest firmware so that they can support the most stringent security options.
The primary focus of this course is on accessing wide area networks (WAN). The goal is to develop an understanding of various WAN technologies to connect small- to medium-sized business networks.
The course introduces WAN converged applications and quality of service (QoS). It focuses on WAN technologies including PPP, Frame Relay, and broadband links. WAN security concepts are discussed in detail, including types of threats, how to analyze network vulnerabilities, general methods for mitigating common security threats and types of security appliances and applications. The course then explains the principles of traffic control and access control lists (ACLs) and describes how to implement IP addressing services for an Enterprise network, including how to configure NAT and DHCP. IPv6 addressing concepts are also discussed. During the course, you will learn how to use Cisco Router and Security Device Manager (SDM) to secure a router and implement IP addressing services.
