In-Depth Information
The 192.168.40.0/24 network must be subnetted using VLSM for all other addresses in
the network:
■
The HQ LAN1 will require 50 host IP addresses.
■
The HQ LAN2 will require 50 host IP addresses.
■
The BRANCH LAN1 will require 30 host IP addresses.
■
The BRANCH LAN2 will require 12 host IP addresses.
■
The link between HQ and BRANCH will require an IP address at each end.
■
Consider the following questions when creating your network design.
Step 2.
How many subnets need to be created from the 192.168.40.0/24 network?
5
How many total IP addresses are required from the 192.168.40.0/24 network?
144, or 148
if you count the Fast Ethernet interfaces
What subnet mask will be used for the HQ LAN1 subnet?
255.255.255.192 or /26
What is the maximum number of host addresses that could be used on this subnet?
62
What subnet mask will be used for the HQ LAN2 subnet?
255.255.255.192 or /26
What is the maximum number of host addresses that could be used on this subnet?
62
What subnet mask will be used for the BRANCH LAN1 subnet?
255.255.255.224 or /27
What is the maximum number of host addresses that could be used on this subnet?
30
What subnet mask will be used for the BRANCH LAN2 subnet?
255.255.255.240 or /28
What is the maximum number of host addresses that could be used on this subnet?
14
What subnet mask will be used for the link between the HQ and BRANCH routers?
255.255.255.252 or /30
What is the maximum number of host addresses that could be used on this subnet?
2
Assign subnetwork addresses to the topology diagram in Figure 7-4.
Step 3.
Assign subnet 0 of the 192.168.40.0 network to the HQ LAN1 subnet. What is the net-
work address of this subnet?
192.168.40.0/26
■
Assign subnet 1 of the 192.168.40.0 network to the HQ LAN2 subnet. What is the net-
work address of this subnet?
192.168.40.64/26
■
Assign subnet 2 of the 192.168.40.0 network to the BRANCH LAN1 subnet. What is
the network address of this subnet?
192.168.40.128 /27
■
Assign subnet 3 of the 192.168.40.0 network to the BRANCH LAN2 subnet. What is
the network address of this subnet?
192.168.40.160 /28
■
Assign subnet 4 of the 192.168.40.0 network to the link between the HQ and
BRANCH routers. What is the network address of this subnet?
192.168.40.176 /30
■
Task 2: Determine Interface Addresses
Assign appropriate addresses to the device interfaces.
Step 1.
Assign the first valid host address in the 209.165.200.224/27 network to the LAN
interface on the ISP router.
