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

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

Phase 6 – Ether Channel
• The company wants to implement Ether Channel.
• In the prototype just implement LACP Ether Channel only for the Nyeri site
Case Study V4.2 Semester 1 2020 – Page 9 of 17
Phase 7 – Configure Routers and Routing Protocol
• Refer to Phase 2 for VLSM subnets and IP Address assignment.
• Refer to Phase 3 for details regarding OSPF.
• The Internet Web Server attached to Chuka ISP has a Class B address (given by your lab tutor). This
Web Server represents the “Internet”.
• Configure a static route on Chuka ISP to the internal network
• For each site, record Router IP address details in table C.
Table C: Router Details
Site: Router Name:

Case Study V4.2 Semester 1 2020 – Page 10 of 17
Phase 8 – Configuring IP Addresses
8.1 DHCP – Kinamba Site
• The company wants to use DHCP.
• In the prototype just implement DHCP only for Kinamba site.
• DHCP must dynamically provide IP address information to PC workstations/Laptops.
• DHCP must manually provide an IP address to the printer
• Use the information documented in Phase 1 to configure each DHCP pool.
• Connect only 1 PC workstation to a switch for each of the appropriate VLANs .
• Label the PCs, for example PCLeasing. This will aid your team and the Tutor in testing the Packet
Tracer prototype
8.2 Other Sites
• Directly configure all devices with an IP address
Table D: Kinamba DHCP Server Pool IP Host Addresses

Table E: Statically assigned IP Host Addresses – Servers, Printers etc
Phase 9 – Configure Frame Relay and PPP
• Configure a Cloud in Packet Tracer as Frame Relay Switch, use it to connect the company’s sites
• Configure PPP and CHAP authentication on the link to the ISP.

Case Study V4.2 Semester 1 2020 – Page 11 of 17
Phase 10 – Wireless LAN Deployment Site
• In the prototype, you will implement a wireless LAN only at the deployment site given in your
specification.
• The Site Security group must have access to the network via the wireless LAN.
• Determine the number of Wireless Access Points that are required at the site to support the Security
group. Show the details of your calculation.
• With the help of graph paper (scan it to include in the report), show to scale the deployment of the
wireless access points across the site.
• In the prototype configure one wireless access point, and test that a Security group laptop can ping
all devices within the site.
Table F: Wireless Access Point Details
Phase 11 – NAT Configuration
The company wants to use private addresses. The addresses provide by your tutor do not actually belong to
the private range, but are sufficient for the purpose of building the prototype network.
1. Configure NAT on the router that is acting as your gateway router to the Internet as follows:
• Define the NAT pool. Please use the Class B NAT pool public address given to you by your lab
tutor.
• Assign a static address to each of the servers.
• The rest of the address range can be used with the NAT pool.
• Define an access control list, which will permit all IP traffic from permitted internal addresses.
• Overload your NAT pool
2. Test that NAT is working from a host on any LAN or VLAN. The host should be able to ping and browse
to the Internet Web Server.

Phase 12 – Access Control at Nakuru Site
The company requires the implementation of ACLs to control the flow of IP traffic within its network and to
the Internet. In the prototype, you will implement Access Control Lists only at the Nakuru site.

a. ACL Rules for Server Farm LAN Access
You must decide the ACL access rules as to which VLANs can access which servers in the Server
Farm VLAN
b. ACL Rules for Group Access VLANs
i. All VLANs are permitted access to Internet unless specifically denied below
