Lab 1.3.1: Review of Concepts from Exploration 1
Topology Diagram

Learning Objectives
Upon completion 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 verifypasswords

Scenario
In this lab, you will design and configure a small routed network and verify connectivity 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 additionalconfiguration. You
will use common commands to test and document the network. The zero subnet is used.

Lab 1.3.1: Review of Concepts from Exploration 1

Task 1: Design a Logical LAN Topology
Step1: Design an IP addressing scheme.
Given the IP address block of 192.168.7.0 /24, design an IP addressing scheme that 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 usablesubnets
(including the 0 subnet)
Number of usable hosts per subnet
IP network address
First IP host address
Last 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.

Host1
Router1-Fa0/0
Host2Router1-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 necessary cables.
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

Step 2: Physically connect lab devices.
Cable the network devices as shown in Figure 1. Turn power on to all devices 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.Note: The following directions are for Windows XP. To configure hosts using other operating systems,
refer to the operating system manual.
To configure the host, go to Start > Control Panel > Network Connections > Local Area
Connection. In the Local Area Connection Properties window, select Internet Protocol (TCP/IP) and
click the Properties button.
