Objectives

Part 1: Calculate Summary Routes

Part 2: Configure Summary Routes

Part 3: Verify Connectivity

Background

In this activity, you will calculate and configure summary routes. Router summarization, also known as route aggregation, is the process of advertising a contiguous set of addresses as a single address.

Part 1:     Calculate Summary Routes

Step 1:     Calculate a summary route on R1 to reach LANs on R3.

a.     List the 172.22.1.128/27 and 172.22.1.160/27 networks in binary format.

172.22.1.128: 10101100.00010110.00000001.10000000

172.22.1.160: 10101100.00010110.00000001.10100000

b.    Count the left-most matching bits to determine the mask for the summary route. They have 26 left-most bits in common.

172.22.1.128: 10101100.00010110.00000001.10000000

172.22.1.160: 10101100.00010110.00000001.10100000

c.     Copy the matching bits and fill in the remaining bits with zeros to determine the summarized network address.

10101100.00010110.00000001.10000000

d.    What is the summarized network address and subnet mask? ___________________________________

Step 2:     Calculate a summary route on R3 to reach LANs on R1 and R2.

a.     Calculate the summary route for the 172.31.157.0/26, 172.31.157.64/27, and 172.31.157.96/30 networks. List the networks in binary format. Then, count the left-most matching bits to determine the mask for the summary route.

b.    What is the summarized network address and subnet mask? ___________________________________

Part 2:     Configure Summary Routes

Step 1:     Configure a summary route for R1.

Configure the recursive summary route that you calculated in Part 1, Step 1

.

Step 2:     Configure a summary route for R3.

Configure the directly attached summary route that you calculated in Part 1, Step 2.

Part 3:     Verify Connectivity

Verify that all PC hosts and routers can ping other PC hosts and routers in the topology. If not, troubleshoot and correct the issues.

Objectives

Part 1: Examine the Network Requirements

Part 2: Design the VLSM Addressing Scheme

Part 3: Assign IP Addresses to Devices and Verify Connectivity

Background

In this activity, you are given a /24 network address to use to design a VLSM addressing scheme. Based on a set of requirements, you will assign subnets and addressing, configure devices and verify connectivity.

Part 1:   Examine the Network Requirements

Step 1:     Determine the number of subnets needed.

You will subnet the network address ______________________. The network has the following requirements:

·         ______________________ LAN will require ______________________ host IP addresses 

·         ______________________ LAN will require ______________________ host IP addresses 

·         ______________________ LAN will require ______________________ host IP addresses 

·         ______________________ LAN will require ______________________ host IP addresses

How many subnets are needed in the network topology? _______

Step 2:     Determine the subnet mask information for each subnet.

a.     Which subnet mask will accommodate the number of IP addresses required for ___________________?

How many usable host addresses will this subnet support? _______

b.    Which subnet mask will accommodate the number of IP addresses required for ___________________?

How many usable host addresses will this subnet support? _______

c.     Which subnet mask will accommodate the number of IP addresses required for ___________________? 

How many usable host addresses will this subnet support? _______

d.    Which subnet mask will accommodate the number of IP addresses required for ___________________?

How many usable host addresses will this subnet support? _______

e.     Which subnet mask will accommodate the number of IP addresses required for the connection between ___________________ and ___________________? 

Part 2: Design the VLSM Addressing Scheme

Step 1:     Divide the ______________________. network based on the number of hosts per subnet.

a.     Use the first subnet to accommodate the largest LAN.

b.    Use the second subnet to accommodate the second largest LAN.

c.     Use the third subnet to accommodate the third largest LAN.

d.    Use the fourth subnet to accommodate the fourth largest LAN.

e.     Use the fifth subnet to accommodate the connection between ___________________ and ___________________.

Step 2:     Document the VLSM subnets.

Complete the Subnet Table, listing the subnet descriptions (e.g. ___________________ LAN), number of hosts needed, then network address for the subnet, the first usable host address, and the broadcast address. Repeat until all addresses are listed.

Subnet Table

Subnet Description	Number of Hosts Needed	Network Address/CIDR	First Usable Host Address	Broadcast Address

Step 3:     Document the addressing scheme.

a.     Assign the first usable IP addresses to ___________________ for the two LAN links and the WAN link.

b.    Assign the first usable IP addresses to ___________________ for the two LANs links. Assign the last usable IP address for the WAN link.

c.     Assign the second usable IP addresses to the switches.

d.    Assign the last usable IP addresses to the hosts.

Part 3: Assign IP Addresses to 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 ___________________ LAN interfaces.

Step 2:     Configure IP addressing on ___________________, including the default gateway.

Step 3:     Configure IP addressing on ___________________, including the default gateway.

Step 4:     Verify connectivity.

You can only verify connectivity from ___________________, ___________________, and ___________________. However, you should be able to ping every IP address listed in the Addressing Table.
