Objectives
Part
1: Design an IP Addressing Scheme
Part
2: Assign IP Addresses to Network Devices and Verify Connectivity
Scenario
In this activity, you are given the network
address of 172.31.1.0 /24 to subnet and provide the IP addressing for the
network shown in the Topology. The required host addresses for each WAN and LAN
link are labeled in the topology.
Part 1:
Design an IP Addressing Scheme
Step 1:
Subnet the 172.31.1.0/24
network based on the maximum number of hosts required by the largest subnet.
a.
Based on the topology, how many
subnets are needed? _______
b.
How many bits must be borrowed
to support the number of subnets in the topology table? _______
c.
How many subnets does this
create? _______
d.
How many usable host addresses does
this create per subnet? _______
Note: If your answer is less than the 14 maximum hosts required for the
R3 LAN, then you borrowed too many bits.
e.
Calculate the binary value for
the first five subnets. Subnet zero is already shown.
Net 0: 172 . 31 . 1 . 0
0 0 0
0 0 0 0
Net 1: 172 . 31 . 1 . ___ ___ ___ ___ ___ ___ ___

f.
Calculate the binary and
decimal value of the new subnet mask.

g.
Complete the Subnet Table, listing all available subnets, the first and last usable host
address, and the broadcast address. The first subnet is done for you. Repeat
until all addresses are listed.
Note: You may not need to use all rows.

Step 2:
Assign the subnets to the
network shown in the topology.
When assigning the subnets, keep in mind
that routing is necessary to allow information to be sent throughout the
network.
a.
Assign Subnet 0 to the R1 LAN: ___________________
b.
Assign Subnet 1 to the R2 LAN: ___________________
c.
Assign Subnet 2 to the R3 LAN: ___________________
d.
Assign Subnet 3 to the R4 LAN: ___________________
e.
Assign Subnet 4 to the link
between __________________________
f.
Assign Subnet 5 to the link
between __________________________
g.
Assign Subnet 6 to the
link between __________________________
Step 3:
Document the addressing scheme.
Complete the Addressing Table using the following guidelines:
a.
Assign the first usable IP
addresses to routers for each of the LAN links.
b.
Use the following method to
assign WAN link IP addresses:
·
For the WAN link between R1 and
R2, assign the first usable IP address to R1 and last usable IP address R2.
·
For the WAN link between R2 and
R3, assign the first usable IP address to R2 and last usable IP address R3.
·
For the WAN link between R3 and
R4, assign the first usable IP address to R3 and last usable IP address R4.
c.
Assign the second usable IP
addresses to the switches.
d.
Assign the last usable IP
addresses to the hosts.
Part 2:
Assign IP Addresses to Network
Devices and Verify Connectivity
Most of the IP addressing is already configured
on this network. Implement the following steps to complete the addressing
configuration.
Step 1:
Configure IP addressing on R1
and R2 LAN interfaces.
Step 2:
Configure IP addressing on S3,
including the default gateway.
Step 3:
Configure IP addressing on PC4,
including the default gateway.
Step 4:
Verify connectivity.
You can only verify connectivity from R1,
R2, S3, and PC4. However, you should be able to ping every IP address listed in
the Addressing Table.
