Lab 1.3.1: Review of Concepts from Exploration 1

(Instructor Version)

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 verify passwords

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 additional configuration. You

will use common commands to test and document the network. The zero subnet is used.

Appendix 1 contains a subnet chart for the last IPv4 octet.

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 scheme that satisfies the

following requirements:

Subnet

Number of Hosts

Subnet A

110

Subnet B

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)

11111111. 11111111. 11111111.10000000

New IP mask (decimal)

255.255.255.128

Maximum number of usable

subnets (including the 0 subnet)

Number of usable hosts per

subnet

126

IP subnetwork address

192.168.7.0

First IP host address

192.168.7.1

Last IP host address

192.168.7.126

Subnet B

Specification

Student Input

Number of bits in the subnet

IP mask (binary)

11111111. 11111111.

11111111.11000000

New IP mask (decimal)

255.255.255.192

Maximum number of usable subnets

(including the 0 subnet)

Number of usable hosts per subnet

IP network address

192.168.7.128

First IP host address

192.168.7.129

Last IP host address

192.168.7.190

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 IP address Mask Gateway

Host1 192.168.7.1 255.255.255.128 192.168.7.126

Router1-Fa0/0 192.168.7.126 255.255.255.128 -------------

Host2 192.168.7.129 255.255.255.192 192.168.7.190

Router1-Fa0/1 192.168.7.190 255.255.255.192 -------------

Table 1. IP Address Assignments

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 Cable Type

LAN cable between Host1 and Router1 Fa0/0 Crossover

LAN cable between Switch1 and Router1 Fa0/1 Straight-through

LAN cable between Switch1 and Host2

Straight-through

Console cable between Host1 and Router1

Rollover

Figure 1. Cabling the network

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.

Instructor note: Ensure that the switch is in the default configuration and that Fa0/1 and Fa0/2

are in Vlan1. Ensure that the router configuration has been erased.

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.

Figure 2. Setting Properties for Internet Protocol (TCP/IP)

In the TCP/IP Properties dialog box for each host, enter the IP address, network mask, and

the gateway from Table 1.

After configuring each host computer, open a command window on the host by selecting

Start > Run . When prompted to type the name of a program, enter cmd in the text box. From

the command window, display and verify the host network settings with the ipconfig /all

command. The settings should match those in the tables below:

Host1 Network Configuration

IP address

192.168.7.1

Subnet mask

255.255.255.128

Default gateway

192.168.7.126

Host2 Network Configuration

IP address

192.168.7.129

Subnet mask

255.255.255.192

Default gateway

192.168.7.190

Are the host settings in agreement with the tables? ___________ If not, reconfigure as necessary.
