Network Design and Implementation Case Study - IT Assignment Help

Assignment Task:

Task:

Phase 1 - Case Study Overview Best Vehicles R Us Ltd is a company that leases buys and sells and repairs cars, trucks and buses. The Head Office is at the Nakuru site. The other company sites are in Kinamba, Chuka and Nyerin. The company is implementing a network that should support potential growth over the next five years. The task is to design, implement and fully document the proposed Best Vehicles R Us Company network. You must prepare:

1. A Written Report 2. A Video Presentation were each member of the team outlines their contributions to the project 3. A prototype of the network, built using Packet Tracer V7 as a proof of concept that your team can build a network that will satisfy the company’s requirements.

4. Please note the following:

• You have 10 weeks (which includes the Mid-Semester Break) to complete the case study. It is important to form your team and get your specifications from a tutor early.

• Given the nature of the case study, it is not possible to cover all the required knowledge in lectures before you start and finish the case study. However, unit lecture material and CISCO guides are available on Canvas for you to reference. You can also access information on the Cisco company website

• The case study is: o a team assessment for first time students o an individual assessment for repeating students.

• In forming a team: it is the responsibility of each student to negotiate with other students within the unit to form the team.

• This case study requires the building and configuration of a network using skills gained through studying the Unit material.

• It is important to read and understand each requirement to ensure that the case study is completed accurately.

• The get following information from a Tutor !

o Specification Number (Spec No)

o Pseudo private Class A Internal network address (to ensure uniqueness between assignments)

o Class B NAT Pool Public IP address range

o Class C ISP Network Connection IP addresses

o Class B ISP Internet Web Server IP address o Wireless deployment site

o Expected Percentage Growth of staff for VLSM design o Switch Management VLAN number Case Study V4.2 Semester 1 2020 - Page 5 of 17 5. Company Site Layouts At Nakuru:

Phase 2 – IP addressing and VLSM Design The Best Vehicles R Us Company require you to use Packet Tracer V7 for development and demonstration of the prototype. The prototype does not need to have in it all the devices that would be required in the actual physical implementation. In implementing your VLSM design, you need to consider the following:

1. The Company workgroups

• Nakuru o Leasing group o Marketing group o Business group

• Kinamba o Leasing group

• Nyeri o Sales group

• Chuka o Sales group

• All Sites o Security group o Technical Support group o Vehicle Servicing group 2. The number of staff Each staff member will have either a desktop PC or a Laptop PC.

• Nakuru

• 125 staff in the Leasing group

• 180 staff in the Marketing group

• 200 staff in the Business group • Kinamba • 80 staff in the Leasing group

• Nyeri

• 140 staff in the Sales group.

• Chuka

• 125 staff in the Sales group

• All sites

• 20 staff in the Security group, 5 staff at each site.

• 20 staff in the Technical Support group, 5 staff at each site

• 20 staff in the Vehicle Servicing group, 5 staff at each site 3. Server Farm

• Separate company Server Farm VLAN at the Nakuru site. You can decide the number and type of servers required. You must allow for IP address space for the Server farm in your VLSM design. Case Study V4.2 Semester 1 2020 - Page 7 of 17 4. Switch Management VLANs

• A Switch Management VLAN must be created at each site

• For the Management VLAN number refer to your specifications 5. Printers and Photocopiers

• Allow for 1 printer and 1 photocopier for at each company site 6. VLSM Implementation The company requires the use of VLSM Design to ensure efficient use of the IP address space.

• Use pseudo private class A network (refer to your specifications) for internal addressing

• Take into account the for expected % growth (refer to your specifications) of current IP requirements when determining size of subnets.

• Clearly identify ip address that are available for future use.

• Record details in table A to show the subnets that meet the Company requirements. Table A: VLSM Design Number of host addresses required Subnet Network Address Subnet Mask Subnet Prefix Max Number of Hosts Possible Address Space Future Use Y/N VLAN Name Site Location Case Study V4.2 Semester 1 2020 - Page 8 of 17

Phase 3 – Routing Protocol Planning The company network will use OSPF as the routing protocol:

• OSPF MD5 authentication is required on the link between Nakuru and Chuka routers

• The bandwidth on all internal router to router links must be set to 512

• Set passive interface for relevant interfaces

• Configure a default route to Chuka ISP

• Advertise default route to other internal routers

• Nakuru Only: router must be accessible via SSH for maintenance by Technical Support group

Phase 4 – Switch and VLAN Planning

• All sites o Rather than use VLAN 1 as the default management VLAN at each site, configure a Management VLAN with VLAN number provided by your specifications. All switches will be in this Management VLAN. o All unallocated switch ports must be shutdown o All access switches must have one access port for each VLAN configured, except for the Management VLAN

• Kinamba Only: access switch ports must be secured using port security • Chuka Only: access switches require path redundancy to a distribution switch. The distribution switch must be configured as the route bridge for all VLANs

• Nakuru Only: switches at this site must be accessible via SSH for maintenance by Technical Support group

Phase 5 – Configure Switches, VLANs

• Refer to Phases 2, 4

 

• There must be a PC (clearly identified and connected eg PC Sales) on each VLAN to allowing testing of the network

• For each site, record Switch details in table B: Table B: Switch Details Name Model # of Ports Location Management VLAN IP Address Default Gateway IP Address Management Vlan VTP Mode VTP Domain

Phase 6 – Ether Channel

• The company wants to implement Ether Channel.

• In the prototype just implement LACP Ether Channel only for the Nyeri site
