Introduction to Lab 8.5 4.3

This lab, Lab 8.5 4.3, will give you hands-on experience setting up a network using switches and routers so you can gain a better understanding of networking fundamentals. This lab is part of our ongoing series that delves into the intricacies of network construction, management, and troubleshooting.


This lab’s primary objective is to provide you with the skills necessary to construct a basic network infrastructure that utilizes switches and routers. In this session, you will learn how to configure network devices, understand their roles within a network, and troubleshoot common networking problems.

Materials Needed:

  • Network switches
  • Routers
  • Ethernet cables (straight-through and crossover)
  • PCs or laptops to test connectivity
  • Network diagrams for reference

Lab Overview:

In this lab, you will be tasked with the following:

  • Designing a Network Topology: In this step, you will use a schematic representation of your intended network, which will include an arrangement of routers, switches, and end devices.
  • Configuring Switches: This step requires you to create VLANs, assign switch ports, and verify that the switches are functioning properly to forward traffic within the local network.
  • Setting Up Routers: Setting up routing protocols will facilitate data transmission to and from external networks by configuring routers for inter-network communication.
  • Testing and Verification: Through various command-line utilities, you will verify the connectivity and performance of your network.
  • Troubleshooting: As problems arise, you will diagnose and solve them using systematic troubleshooting techniques.

Expected Outcomes:

At the completion of Lab 8.5 4.3, you should be able to:

  • Identify the functions of switches and routers in a network.
  • Ensure that devices are configured according to a specified network design.
  • Identify and resolve connectivity problems effectively.
  • For maintenance and scaling purposes, it is necessary to document network configurations.


Ensure you have reviewed the relevant chapters on network devices and protocols before commencing with this lab. Also, you should be familiar with the command-line interface (CLI) of routers and switches.

The creation of a network using switches and routers is a fundamental task for networking students and IT professionals. To understand how data is transmitted across devices, one often sets up a lab environment where a network can be simulated. The keyword “8.5 4.3 lab building a switch and router network” suggests a specific lab exercise, likely from a networking course or training manual, which focuses on constructing a network using switches and routers.

When undertaking such a lab, the process typically involves the following steps:

  • Planning the Network Topology: During this initial stage, you need to decide how the network devices will be connected. For a basic setup, this may involve a few switches and routers to create a local area network (LAN) and a connection to a wide area network (WAN).
  • Gathering Equipment: It is necessary to procure switches, routers, modems, PCs, servers, and cables to complete this lab. The numbers 8.5 and 4.3 may refer to the model numbers or versions of the devices used in the lab.
  • Configuring the Switches: There are a number of things that you will need to accomplish in this step, including initializing the switches, creating VLANs (Virtual Local Area Networks), and ensuring that they can communicate with one another. You may also have to configure trunk ports if there are more than one VLAN.
  • Configuring the Routers: Set up of routers involves setting up interfaces, IP addresses, and routing protocols such as OSPF and EIGRP to enable them to route traffic between different networks.
  • Testing Connectivity: Using commands such as ping, traceroute, and checking the routing tables, you would verify network connectivity after the switches and routers have been configured.
  • Troubleshooting: It is necessary to diagnose and understand the flow of packets through the network in this step if there is a problem with connectivity. It is also necessary to make adjustments to the configuration of the network if necessary.
  • Documenting the Network: For future reference and troubleshooting, it is important to document the network setup, including IP addresses, topology diagrams, and device configurations.
  • Review and Learning: As a final step, reviewing the setup process, the configurations, as well as the troubleshooting steps taken to ensure network connectivity is critical to understanding networking concepts on a deeper level.

Providing hands-on learning about networking principles, device configurations, and network troubleshooting through this type of lab activity is vital in educational settings. As a result, students are prepared to design, implement, and manage networks that are critical to business operations and communication in real-world scenarios.


How do I establish a connection between a router and a switch?

As you hold the Ethernet cable in your hands, securely connect one end of the cable to the switch’s Ethernet port. Next, connect the opposite end of the cable to the router’s Ethernet port. To ensure a reliable connection, ensure a tight and secure fit is maintained.

How many routers and switches do I need for the CCNA lab?

What constitutes the optimal CCNA lab configuration? It’s quite straightforward: three routers, three switches, and a pair of laptops. This is the minimum setup Cisco recommends for setting up a network tailored for CCNA certification. It is possible to continue using the same equipment as you progress to CCNP and CCIE levels, perhaps adding one or two more routers to enhance complexity and proficiency.

What is between the router and switch?

In contrast to a switch, routers have a primary objective of facilitating connections between multiple networks simultaneously, functioning primarily on the network layer. A switch, on the other hand, facilitates the simultaneous connection of multiple devices within a network.

Which wire is used to connect the router and switch?

In computer networking, you’ll often encounter two common types of Ethernet cables: straight-through cables. These cables find frequent use in local area networks, linking various devices together. For instance, they connect computers to network hubs like routers, routers to switches, PCs to switches, and more.

What is the minimum score for CCNA?

The CCNA exam strikes a balance, offering a challenge that’s neither overly daunting nor too straightforward. It is imperative to prepare adequately for the CCNA exam in order to achieve a minimum score of 800 out of 1000. Questions on the exam include multiple-choice questions, drag-and-drop assignments, as well as simulations.


I found the 8.5 4.3 lab to be an enlightening experience as I explored the intricacies of building a switch and router network. We have discussed the concepts and techniques necessary to construct a robust network infrastructure. With this newfound understanding, you are now better prepared to navigate the ever-evolving field of networking. 

The key to mastering this dynamic field is practice and continuous learning. Take the confidence you gained from this laboratory experience and let it propel you to even greater heights in your networking career. This program has boundless possibilities, and the skills you will gain here will serve you well in your pursuit of networking excellence.
