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.

LAN Switching and Wireless: LAN Design 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 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 1

IP mask (binary) 11111111. 11111111. 11111111.10000000 New IP mask (decimal) 255.255.255.128

Maximum number of usable subnets (including the 0 subnet)

2 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

(3)

IP mask (binary) 11111111. 11111111. 11111111.11000000 New IP mask (decimal) 255.255.255.192 Maximum number of usable subnets

(including the 0 subnet)

2 Number of usable hosts per subnet 62 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.
