CMIT 351 Project 2: Design and Implement a Routed LAN
CMIT 351 Project 2 Description
Intro:
ACME University IT has reviewed the results from your prototype and now wants to move
forward with an adjusted set of requirements. You will need to implement layer 2 segmentation
to control broadcast domains and increase Local Area Network (LAN) performance but also
provide routing between segments.
Scenario:
IT has tasked you with implementing the revised, routed LAN. This effort builds on the
prototype you recently completed. As always, you need to document all your work. The
requirements you have specify a maximum number of switches (1), the number of virtual LANs
(VLANs) as four, one router, and some computers in each VLAN for endpoint testing.
Overview
Modern switches use VLANs to improve network performance by separating large Layer 2
broadcast domains into smaller ones. In general, VLANs make it easier to design a network to
support the goals of an organization. However, VLANs are not able to intercommunicate without
the addition of layer 3 routing. A router or similar capability is required to facilitate inter-VLAN
communication. Additionally, trunking will be required between network layers.
Objectives
• Design a routed Local Area Network using switches, routers, and hosts (computers)
• Describe basic switch configuration necessary for switch maintenance and operation
• Describe basic router configuration necessary for router maintenance and operation
• Describe Virtual LANs (VLANs) configurations to enforce segmentation
• Describe router interface configuration necessary facilitate inter-VLAN routing
• Describe necessary VLAN trunking between the switch and router
Tools
• You will need a diagramming application such as draw.io or Visio to complete Part 1.
• You can reference the following uCertify labs for help in building the switch
configuration narratives: Modules 5, 6, 7, 8, 9, 10, 15, and 17
• Note: access to physical or emulated Cisco devices is not required to complete this
project. However, if you want to test, practice, or otherwise tinker you can get Cisco
Packet Tracer (https://skillsforall.com/course/getting-started-cisco-packet-tracer) or
GNS3 (https://www.gns3.com/)
Submission:
Use the Project 2 Template document for your submission. Fundamentally, you need to submit
two things: (a) a network diagram and (b) descriptions of the configurations outlined in the
objectives above.
Version 1.0
Part 1: Design the Local Area Network
The work milestones for this part of the project are as follows:
• The total LAN must consist of 1 switch, 1 Router and 4 computers.
• The switch must be named S1.
• The router must be named R1.
• The four computers must be named PC-A, PC-B, PC-C, and PC-D.
Part 2: Create the basic switch and router configurations
Your network engineering lead has approved the LAN design. Now, the work to implement the
design can begin. Your tasks are as follows:
2.1 Cable the network
• Connect S1 Ethernet Interface 1 to R1 Ethernet Interface 1
• Connect PC-A to S1 on Ethernet Interface 4
• Connect PC-B to S1 on Ethernet Interface 6
• Connect PC-C to S1 on Ethernet Interface 11
• Connect PC-D to S1 on Ethernet Interface 13
2.2. Configure the basic switch and router functions
Configure the basic functions in S1 and R1 as follows:
• Set the enable secret to “class”
• Set the line con 0 password to “cisco”
• Set the line vty 0 15 password to “cisco”
• Set the MOTD to “Unauthorized access is strictly prohibited.”
• Set logging to synchronous
2.3 Configure the computers
Configure the four computers as follows:
Name IP Address Subnet Gateway
PC-A 192.168.10.3 255.255.255.0 192.168.10.1
PC-B 192.168.20.4 255.255.255.0 192.168.20.1
PC-C 192.168.30.5 255.255.255.0 192.168.30.1
PC-D 192.168.40.6 255.255.255.0 192.168.40.1
2.4 Test and Validate Connectivity
Use ping to test connectivity between the computers. Detail your results in your project
document, both what works and what doesn’t work.
Part 3: Define the VLANs
3.1 You need to define four VLANs on the switch as follows:
• VLAN 10 Students
• VLAN 20 Faculty
• VLAN 30 Management
• VLAN 99 Containment
Version 1.0
3.2 Then, define the following interfaces for the VLANs as:
Device Interfaces VLAN / IP Address
S1 4 VLAN 10
S1 6 VLAN 20
S1 11 VLAN 30
S1 2-3,5,7-10,12-24 VLAN 99
R1 Ethernet Interface 1, subinterface 10 192.168.10.1 255.255.255.0
R1 Ethernet Interface 1, subinterface 20 192.168.20.1 255.255.255.0
R1 Ethernet Interface 1, subinterface 30 192.168.30.1 255.255.255.0
Part 4: Implement VLAN Trunking
4.1 Implement VLAN trunking on the switch as follows:
• Manually set interface 1 on S1 to trunk (do not use mode dynamic desirable)
• Manually set Interface 1, subinterface 10 on R1 for 802.1Q encapsulation in VLAN 10
• Manually set Interface 1, subinterface 20 on R1 for 802.1Q encapsulation in VLAN 20
• Manually set Interface 1, subinterface 30 on R1 for 802.1Q encapsulation in VLAN 30
4.2 Use ping to test connectivity between the computers and switches. Detail your results in your
project document, both what works and what doesn’t work. Pay close attention to PC-D!
