Task 1: Examine the Network Requirements
Examine the network requirements and answer the questions that follow. Keep in mind that IP
addresses will be needed for each of the LAN interfaces.
How many LAN subnets are needed? 18
1.
How many subnets are needed for the WAN links between routers? 13
2.
How many total subnets are needed? 31
3.
What is the maximum number of host IP addresses that are needed for a single subnet? 8000
4.
What is the least number of host IP addresses that are needed for a single subnet? 125
5.
How many IP addresses are needed for the East portion of the network? Be sure to include the
WAN links between the routers as well as an IP address for each LAN interface. 11,774
6.
How many IP addresses are needed for the West portion of the network? Be sure to include the
WAN links between the routers as well as an IP address for each LAN interface. 14,016
7.
How many IP addresses are needed for the Central portion of the network? Be sure to include
the WAN links between the routers as well as an IP address for each LAN interface. 12,004
8.
What is the total number of IP addresses that are needed? 37,794
9.
What is the total number of IP addresses that are available in the 172.16.0.0/16 network?
65,534
10.
Can the network addressing requirements be met using the 172.16.0.0/16 network? yes
11.
Task 2: Divide the Network into Three Subnetworks
Determine the subnet information for each network section.
Step 1.
To keep the subnets of each of the major network sections contiguous, begin by creating a
main subnet for each of the East, West, and Central network sections.
What is the smallest-size subnet that can be used to meet the addressing requirement
for the East network? /18
1.
What is the maximum number of IP addresses that can be assigned in this size
subnet? 16,382
2.
What is the smallest-size subnet that can be used to meet the addressing requirement
for the West network? /18
3.
What is the maximum number of IP addresses that can be assigned in this size
subnet? 16,384
4.
What is the smallest-size subnet that can be used to meet the addressing requirement
for the Central network? /18
5.
What is the maximum number of IP addresses that can be assigned in this size
subnet? 16,384
6.
Assign subnets.
Step 2.
Start at the beginning of the 172.16.0.0/16 network. Assign the first available subnet
to the East section of the network.
