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 maximum number of IP addresses that are needed for a single subnet?
21
How many IP addresses are needed for each of the branch LANs?
11
What is the total number of IP addresses that are needed?
69
Task 2: Design an IP Addressing Scheme
Subnet the 192.168.9.0 network into the appropriate number of subnets.
Step 1.
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 Table 3-6 with the subnet information.

Assign the subnets to the network shown in the topology diagram in Figure 3-3.
Step 2.
When assigning the subnets, keep in mind that routing will need to occur to allow infor-
mation to be sent throughout the network. The subnets will be assigned to the networks to
allow route summarization on each of the routers.
Assign subnet 1 to the BRANCH2 LAN 2:
192.168.9.32 /27
1.
Assign subnet 2 to BRANCH2 LAN 1 subnet address:
192.168.9.64 /27
2.
Assign subnet 3 to link from HQ to BRANCH2 subnet address:
192.168.9.96 /27
3.
Assign subnet 4 to HQ LAN subnet address:
192.168.9.128 /27
4.
Assign subnet 5 to link from HQ to BRANCH1 subnet address:
192.168.9.160 /27
5.
Assign subnet 6 to BRANCH1 LAN 2 subnet address:
192.168.9.192 /27
6.
Assign subnet 7 to BRANCH1 LAN 1 subnet address:
192.168.9.224 /27
