The Configure, Verify, and Troubleshoot IPv4 Addressing and Subnetting module provides you with the instructions and Cisco hardware to develop your hands on skills in subnetting and configuring IPv4 addressing on a network. This module includes the following activities:

  • Determine the addressing scheme that will be applied to the lab topology
  • Assign IP addresses to interfaces on network and end user devices according to the addressing scheme
  • Verify the IP addressing configuration
  • Examine common misconfigurations that can occur when IP addressing
  • Troubleshoot and resolve network problems due to IP addressing misconfigurations

Exercise 1 - Perform Subnetting to Determine an Addressing Scheme

Before implementing any devices, you will have to determine the IP addresses and subnets that will be assigned on the network and which portions and devices of the network will have which subnets assigned to them. This planning process is critical to the success of your configurations because it gives you a general overview of the whole network. It is often very tempting to go right into the command line and begin configurations, however, this will almost always result in loss of time and effort.

In this exercise, you will perform the necessary subnetting to configure the network fully.

Exercise 2 - Implement an IP Addressing Scheme

You will now implement the IP addressing scheme you created in Exercise 1.

Exercise 3 - Verifying and Troubleshooting the Implemented IP Address Scheme

In this exercise, you will verify that the configuration you applied is working correctly. You will also simulate misconfigurations on the network and examine their implications.
