Objectives
In this lab you will design a VLSM addressing scheme given a network address and host requirements. You will configure addressing on routers, switches, and network hosts.
- Design a VLSM IP addressing scheme given requirements.
- Configure addressing on network devices and hosts.
- Verify IP connectivity.
- Troubleshoot connectivity issues as required.
Background / Scenario
You have been asked to design, implement, and test an addressing scheme for a customer. The customer has given you the network address that is suitable for the network, the topology, and the host requirements. You will implement and test your design.
Instructions
You have been given the network address 10.1.1.0/24 by your customer. The host address requirements are:

| LAN | Number of Addresses Required |
|---|---|
| WS-2 LAN | 47 |
| ES-2 LAN | 28 |
| ES-1 LAN | 11 |
| WS-1 LAN | 5 |
Design Requirements
- Create the addressing design. Follow guidelines provided in the curriculum regarding the order of the subnets.
- The subnets should be contiguous. There should be no unused address space between subnets.
- Provide the most efficient subnet possible for the point-to-point link between the routers.
- Document your design in a table such as the one below.

Configuration Requirements
Note: You will configure addressing on all devices and hosts in the network.
- Assign the first usable IP addresses in the appropriate subnets to East for the two LAN links and the WAN link.
- Assign the first usable IP addresses in the appropriate subnets to West for the two LANs links. Assign the last usable IP address for the WAN link.
- Assign the second usable IP addresses in the appropriate subnets to the switches.
- The switch management interface should be reachable from hosts on all of the LANs.
- Assign the last usable IP addresses in the appropriate subnets to the hosts.
If the addressing design and implementation are correct, all hosts and devices should be reachable over the network.

- The subnets should be contiguous. There should be no unused address space between subnets.
- Provide the most efficient subnet possible for the point-to-point link between the routers.
- Document your design in a table such as the one below.
| Subnet Description | Number of Hosts Needed | Network Address/CIDR | First Usable Host Address | Last Usable Host Address | Broadcast Address |
|---|---|---|---|---|---|
| PS-101 LAN | 32 | 192.168.203.0/26 | 192.168.203.1 | 192.168.203.62 | 192.168.203.63 |
| PD-1 LAN | 21 | 192.168.203.64/27 | 192.168.203.65 | 192.168.203.94 | 192.168.203.95 |
| PS-115 LAN | 19 | 192.168.203.96/27 | 192.168.203.97 | 192.168.203.126 | 192.168.203.127 |
| PD-2 LAN | 14 | 192.168.203.128/28 | 192.168.203.129 | 192.168.203.142 | 192.168.203.143 |
| WAN Link | 2 | 192.168.203.144/30 | 192.168.203.145 | 192.168.203.146 | 192.168.203.147 |

Configuration Requirements
Note: You will configure addressing on all devices and hosts in the network.
- Assign the first usable IP addresses in the appropriate subnets to Police for the two LAN links and the WAN link.
- Assign the first usable IP addresses in the appropriate subnets to Schools for the two LANs links. Assign the last usable IP address for the WAN link.
- Assign the second usable IP addresses in the appropriate subnets to the switches.
- The switch management interface should be reachable from hosts on all of the LANs.
- Assign the last usable IP addresses in the appropriate subnets to the hosts.
If the addressing design and implementation are correct, all hosts and devices should be reachable over the network.
