Learning Objectives
Upon completion of this lab, you will be able to:
Determine the number of subnets needed.
Determine the number of hosts needed.
Design an appropriate addressing scheme.
Assign addresses and subnet maskpairs to device interfaces and hosts.
Examine the use of the available network address space.
Determine how static routing could be applied to the network.
Scenario
In this lab, you have been given the network address 192.168.9.0/24 to subnet and provide the IP addressing for the network shown in the Topology Diagram. The network has the following addressing requirements:
The BRANCH1 LAN 1 willrequire 10 host IP addresses.
The BRANCH1 LAN 2 will require 10 host IP addresses.
The BRANCH2 LAN 1 will require 10 host IP addresses.
The BRANCH2 LAN 2 will require 10 host IP addresses.
The HQ LAN will require 20 host IP addresses.
The link from HQ to BRANCH1 will require an IP address for each end of the link.
The link from HQ to BRANCH2 will require an IP address for each end of thelink.
* (Note: Remember that the interfaces of network devices are also host IP addresses and are included in the above addressing requirements.)
Task 1: Examine the Network Requirements.
Examine the network requirements and answer the questions below. Keep in mind that IP addresses will be needed for each of the LAN interfaces.
How many subnets are needed? _____7_____
What is the maximumnumber of IP addresses that are needed for a single subnet? _____20_____
How many IP addresses are needed for each of the branch LANs? _____10_____
What is the total number of IP addresses that are needed? _____64_____
Task 2: Design an IP Addressing Scheme.
Step 1: Subnet the 192.168.9.0 network into the appropriate number of subnets.
What will the subnet mask be for the subnetworks?_____________255.255.255.224 or /27_____________
How many usable host IP addresses are there per subnet? _____30_____

Fill in the following chart with the subnet information.

Subnet Number | Subnet Address | First Usable
Host Address | Last Usable
Host Address | Broadcast Address |
0 | 192.168.9.0 | 192.168.9.1 | 192.168.9.30 | 192.168.9.31 |
1 | 192.168.9.32 | 192.168.9.33 | 192.168.9.62 |192.168.9.63 |
2 | 192.168.9.64 | 192.168.9.65 | 192.168.9.94 | 192.168.9.95 |
3 | 192.168.9.96 | 192.168.9.97 | 192.168.9.126 | 192.168.9.127 |
4 | 192.168.9.128 | 192.168.9.129 | 192.168.9.158 | 192.168.9.159 |
5 | 192.168.9.160 | 192.168.9.161 | 192.168.9.190 | 192.168.9.191 |
6 | 192.168.9.192 | 192.168.9.193 | 192.168.9.222 | 192.168.9.223 |
7 | 192.168.9.224 | 192.168.9.225 |192.168.9.254 | 192.168.9.255 |
Step 2: Assign the subnets to the network shown in the Topology Diagram.
When assigning the subnets, keep in mind that routing will need to occur to allow information to be sent throughout the network. The subnets will be assigned to the networks to allow for route summarization on each of the routers.
1. Assign first subnet (lowest subnet) to the LAN...
