Overview

Introduction

The Configure and verify IPv4 addressing and subnetting module provides you with the instructions and Cisco hardware to develop your hands on skills in configuring IPv4 addressing manually and configuring DHCP services, this module contains the following exercises:

  1. Configuring IPv4 addressing
  2. Address Resolution Protocol (ARP)
  3. DHCP

Exercise 1 - Configuring IPv4 addressing

In this exercise you will configure some common IPv4 addresses. Hopefully you will have learnt how to subnet in your course material, here we will use some of those skills to configure some address ranges based the requirements list below:

  1. Build an IP addressing plan to suit the WAN connectivity between NYEDGE1, NYEDGE2 and NYWAN1.
  2. Create 4 subnet ranges for VLANs 10, 20, 30 and 40 on the NYCOREx switches, these should meet the following requirements:

a) Each subnet must be able to contain 45 usable host addresses

b) They must be able to be summarized

c) Create 2 point-to-point networks between NYEDGE1 and NYCORE1, then NYEDGE2 and NYCORE2

Exercise 2 - Address Resolution Protocol (ARP)

ARP is fundamental for IPv4 communications across the network. In this exercise you will look at the ARP cache on the routers to see how ARP maps IP Addresses to MAC addresses.

Exercise 3 - DHCP

In this exercise you will configure a DHCP relay. NYEDGE1 is configured to be a DHCP server for both VLAN 30 and VLAN 40, in this exercise you will see that by configuring a relay on NYCORE1 this will forward the requests to NYEDGE1.
