Cisco I Project Classless/VLSM Network
Project Specifications:
Design and implement a multi-location, private inter-networking strategy for a small, stable commercial organization. This
organization currently has 6 locations as indicated in the diagram on page 1, all located in the continental United States.
Procedure:
Phase 1:
1. Work independently; determine the router position and addressing scheme for the circuit pictured.
2. You will need to use Variable Length Subnet Masking (VLSM) to accomplish the IP addressing scheme.

Phase 2:
Devices and Specifications: Select the appropriate number of devices (switches, Routers and WICs) to meet the network design
requirements.
Switch Considerations: Each location (LAN) is fairly small; the number of devices per location is listed in diagram-1. The number
of switches required at each location will be determined base on the number of hosts connected to the LAN and the number of
available ports per switch. All switches must be accessed virtually for management purposes.
Router Considerations: Corporate headquarters is located in Boston. Connection to the Internet and the associated Internetrelated security considerations are to be provided by another company in a future project. The only consideration required at this
time is that each location requires one router to provide WAN connectivity to other location(s); each router should have the
capability to connect successfully to no more than two full T1 circuits. All routers must be accessed virtually for management
purposes.
Phase 3:
1. Construct the circuit pictured in Packet Tracer and use the classless network address 172.16.1.0/24 for addressing.
2. Use RIP Version 2 as a routing protocol. Commands are listed on the diagram. Use clock rate 64000 for serial “DCE”
interfaces (refer to Basic Configuration sheet for commands).
Configuration task on each router:
 Configure the Router’s Name
 Secure the Routers.
 Configure the Ethernet Interface
 Configure the Serial Interfaces
 Configure the Routing Protocol (RIP version 2)

NAME(config-router)# network 172.16.0.0
NAME(config-router)#exit
ROUTER(config)#exit
Design Considerations:
 All Ethernet connections will be 100BaseT connections
 All Serial connections between sites will utilize T1 (1544kbps), point-to-point connections
 The Company will be using a subnet address 172.16.1.0/24 (Phase 1)
 The only protocol in use is TCP/IP
 Routing Protocol is RIP Version 2 (Phase 3)
 The company wants a simple way to manage connections between sites with a minimum of management by IT personnel
(Phase 3)
 Each location is fairly small; the number of devices per location is listed in the above diagram.
 Design should reflect the best practices within the networking community
Deliverables:

Use Packet Tracer to configure this network and to verify validity. (Phase 3)

Documentation package including:
o subnetting scheme. (Phase 1)
o All configurations (from Routers only)
o Logical diagram of the network including subnetting scheme. (Phase 3)
o Verification of the network operation

Detailed Bill of Materials for Router, Switch & WIC. (Phase 2)
o Half of a page description for each device
 Make, model, capabilities and specifications
 (ex. amount of RAM, flash, number of interfaces, etc….)
o Detailed Cost Estimate for Routers, Switches & WIC. (Phase 2)
 In an Excel sheet: Make and model, number of devices, cost per device and total cost.
Completion Criteria:
 Successful connectivity among all sites. Connectivity is defined by being able to ping from a workstation in Boston to a
workstation in all other Locations. Additionally, since there is no support staff in remote locations, Telnet must be enabled
from the Boston Location to all remote sites. (Phase 3)
 Acceptance of detailed documentation package in electronic format by the client.
