Lab 1.3.1: Review of Concepts from Exploration 1
Topology Diagram

Learning Objectives
Uponcompletion of this lab, you will be able to:
•

Create a logical topology given network requirements

•

Create subnets to meet host requirements

•

Configure the physical topology

•

Configure the logical topology

•

Verify network connectivity

•

Configure and verify passwords

Scenario
In this lab, you will design and configure a small routed network and verifyconnectivity across
multiple network devices. This requires creating and assigning two subnetwork blocks, connecting
hosts and network devices, and configuring host computers and one Cisco router for basic network
connectivity. Switch1 has a default configuration and does not require additional configuration. You
will use common commands to test and document the network. The zero subnet is used.All contents are Copyright © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information.

Lab 1.3.1: Review of Exploration 1

Task 1: Design a Logical LAN Topology
Step 1: Design an IP addressing scheme.
Given the IP address block of 192.168.7.0 /24, design an IP addressing schemethat satisfies the
following requirements:

Subnet
Subnet A
Subnet B

Number of Hosts
110
54

The 0 subnet is used. No subnet calculators may be used. Create the smallest possible subnets that
satisfy the requirements for hosts. Assign the first usable subnet to Subnet A.
Subnet A
Specification

Student Input

Number of bits in the subnet
IP mask (binary)
New IP mask (decimal)Maximum number of usable
subnets (including the 0 subnet)
Number of usable hosts per
subnet
IP subnetwork address
First IP host address
Last IP host address

Subnet B
Specification
Number of bits in the subnet
IP mask (binary)
New IP mask (decimal)
Maximum number of usable subnets
(including the 0 subnet)
Number of usable hosts per subnet
IP network address
First IP host addressLast IP host address

Student Input

Host computers will use the first usable IP address in the subnet. The network router will use the last
usable IP address in the subnet.
Step 2: Write down the IP address information for each device.
Device
Host1
Router1-Fa0/0
Host2
Router1-Fa0/1

Before proceeding, verify your IP addresses with the instructor.

Task 2: Configure the Physical Topology
Step 1: Cable the network.
Refer to the figure and table below for the necessarycables.
Cabling
LAN cable between Host1 and Router1 Fa0/0
LAN cable between Switch1 and Router1 Fa0/1
LAN cable between Switch1 and Host2
Console cable between Host1 and Router1

Cable Type
Crossover

Step 2: Physically connect lab devices.
Cable the network devices as shown in Figure 1. Turn power on to alldevices if it is not already on.
Step 3: Inspect the network connections.
Verify the connections visually.

Task 3: Configure the Logical Topology
Step 1: Configure the host computers.
Configure the static IP address, subnet mask, and gateway for each host computer.
