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.
Instructions
Part 1: Examine the Network Requirements
Step 1: Determine the number of subnets needed.
You will subnet the network address 10.11.48.0/24. The network has the following requirements:
- ASW-1 LAN will require 14 host IP addresses
- ASW-2 LAN will require 30 host IP addresses
- ASW-3 LAN will require 6 host IP addresses
- ASW-4 LAN will require 60 host IP addresses
How many subnets are needed in the network topology? 5
Step 2: Determine the subnet mask information for each subnet.
a. Which subnet mask will accommodate the number of IP addresses required for ASW-1?
255.255.255.240 /28
How many usable host addresses will this subnet support?
14 (10.11.48.97 - 10.11.48.110)
b. Which subnet mask will accommodate the number of IP addresses required for ASW-2?
255.255.255.224 /27
How many usable host addresses will this subnet support?
30 (10.11.48.65 - 10.11.48.94)
c. Which subnet mask will accommodate the number of IP addresses required for ASW-3?
255.255.255.248 /29
How many usable host addresses will this subnet support?
6 (10.11.48.113 - 10.11.48.118)
d. Which subnet mask will accommodate the number of IP addresses required for ASW-4?
255.255.255.192 /26
How many usable host addresses will this subnet support?
62 (10.11.48.1 - 10.11.48.62)
e. Which subnet mask will accommodate the number of IP addresses required for the connection between Building1 and Building2?
255.255.255.252 /30
Part 2: Design the VLSM Addressing Scheme
💡 Pro Tip: Struggling with subnetting? Try our VLSM calculator with step-by-step binary to quickly check your results!
Step 1: Divide the 10.11.48.0/24 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 Building1 and Building2.
Step 2: Document the VLSM subnets.
Complete the Subnet Table, listing the subnet descriptions (e.g. ASW-1 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 | Last Usable Host Address | Broadcast Address |
|---|---|---|---|---|---|
| Host-D LAN | 60 | 10.11.48.0/26 | 10.11.48.1 | 10.11.48.62 | 10.11.48.63 |
| Host-B LAN | 30 | 10.11.48.64/27 | 10.11.48.65 | 10.11.48.94 | 10.11.48.95 |
| Host-A LAN | 14 | 10.11.48.96/28 | 10.11.48.97 | 10.11.48.110 | 10.11.48.111 |
| Host-C LAN | 6 | 10.11.48.112/29 | 10.11.48.113 | 10.11.48.118 | 10.11.48.119 |
| WAN Link | 2 | 10.11.48.120/30 | 10.11.48.121 | 10.11.48.122 | 10.11.48.123 |
Step 3: Document the addressing scheme.
a. Assign the first usable IP addresses to Building1 for the two LAN links and the WAN link.
b. Assign the first usable IP addresses to Building2 for the two LAN 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 the Building1 router LAN interfaces.
Building1(config)# interface gigabitethernet 0/0 Building1(config-if)# ip address 10.11.48.97 255.255.255.240 Building1(config-if)# no shutdown Building1(config-if)# interface gigabitethernet 0/1 Building1(config-if)# ip address 10.11.48.65 255.255.255.224 Building1(config-if)# no shutdown
Step 2: Configure IP addressing on the ASW-3 switch, including the default gateway.
ASW3(config)# interface vlan 1 ASW3(config-if)# ip address 10.11.48.114 255.255.255.248 ASW3(config-if)# no shutdown ASW3(config-if)# exit ASW3(config)# ip default-gateway 10.11.48.113
Step 3: Configure IP addressing on Host-D, including the default gateway.
Step 4: Verify connectivity.
You can only verify connectivity from Building1, ASW-3, and Host-D. However, you should be able to ping every IP address listed in the Addressing Table.
Building1# ping 10.11.48.62
ASW3# ping 10.11.48.113

You will subnet the network address 192.168.72.0/24. The network has the following requirements:
- Sw1 LAN will require 7 host IP addresses
- Sw2 LAN will require 15 host IP addresses
- Sw3 LAN will require 29 host IP addresses
- Sw4 LAN will require 58 host IP addresses
How many subnets are needed in the network topology? 5
Step 2: Determine the subnet mask information for each subnet.
a. Which subnet mask will accommodate the number of IP addresses required for Sw4?
255.255.255.192 /26
How many usable host addresses will this subnet support?
62 (192.168.72.1 - 192.168.72.62)
b. Which subnet mask will accommodate the number of IP addresses required for Sw3?
255.255.255.224 /27
How many usable host addresses will this subnet support?
30 (192.168.72.65 - 192.168.72.94)
c. Which subnet mask will accommodate the number of IP addresses required for Sw2?
255.255.255.224 /27
How many usable host addresses will this subnet support?
30 (192.168.72.97 - 192.168.72.126)
d. Which subnet mask will accommodate the number of IP addresses required for Sw1?
255.255.255.240 /28
How many usable host addresses will this subnet support?
14 (192.168.72.129 - 192.168.72.142)
e. Which subnet mask will accommodate the number of IP addresses required for the connection between Remote-Site1 and Remote-Site2?
255.255.255.252 /30
Part 2: Design the VLSM Addressing Scheme
💡 Pro Tip: Struggling with subnetting? Try our VLSM calculator with step-by-step binary to quickly check your results!
Step 1: Divide the 192.168.72.0/24 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 Remote-Site1 and Remote-Site2.
Step 2: Document the VLSM subnets.
Complete the Subnet Table, listing the subnet descriptions (e.g. User-1 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 | Last Usable Host Address | Broadcast Address |
|---|---|---|---|---|---|
| User-4 LAN | 58 | 192.168.72.0/26 | 192.168.72.1 | 192.168.72.62 | 192.168.72.63 |
| User-3 LAN | 29 | 192.168.72.64/27 | 192.168.72.65 | 192.168.72.94 | 192.168.72.95 |
| User-2 LAN | 15 | 192.168.72.96/27 | 192.168.72.97 | 192.168.72.126 | 192.168.72.127 |
| User-1 LAN | 7 | 192.168.72.128/28 | 192.168.72.129 | 192.168.72.142 | 192.168.72.143 |
| WAN Link | 2 | 192.168.72.144/30 | 192.168.72.145 | 192.168.72.146 | 192.168.72.147 |
Step 3: Document the addressing scheme.
a. Assign the first usable IP addresses to Remote-Site1 for the two LAN links and the WAN link.
b. Assign the first usable IP addresses to Remote-Site2 for the two LAN 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 the Remote-Site1 router LAN interfaces.
Remote-Site1(config)# interface gigabitethernet 0/0 Remote-Site1(config-if)# ip address 192.168.72.129 255.255.255.240 Remote-Site1(config-if)# no shutdown Remote-Site1(config-if)# interface gigabitethernet 0/1 Remote-Site1(config-if)# ip address 192.168.72.97 255.255.255.224 Remote-Site1(config-if)# no shutdown
Step 2: Configure IP addressing on the Sw3 switch, including the default gateway.
Sw3(config)# interface vlan 1 Sw3(config-if)# ip address 192.168.72.66 255.255.255.224 Sw3(config-if)# no shutdown Sw3(config-if)# exit Sw3(config)# ip default-gateway 192.168.72.65
Step 3: Configure IP addressing on User-4, including the default gateway.
Step 4: Verify connectivity.
You can only verify connectivity from Remote-Site1, Sw3, and User-4. However, you should be able to ping every IP address listed in the Addressing Table.
Remote-Site1# ping 192.168.72.62
Sw3# ping 192.168.72.65
C:\> ping 192.168.72.129
