You have been hired as a consultant to design how the routers will
update the routing tables and the company network IP scheme (subnets).
The company has grown significantly in the last three years. Response
time between departments in unbearable. Currently a network analyzer
has shown high utilization and high collision rates. Propose a
solution based on the following configuration:
1. The company is located in five cities across the US, New York City
(headquarters), Atlanta, Chicago, Kansas City and San Diego. Each site
has between 750-1100 employees.
2. The company is in the process of obtaining 18 Cisco routers.
3. All the executive managers are located in NY. The Accounting
department is also located in NY.
4. Payroll is processed in NY, but each location has a small
Payroll/HR department.
5. The MIS department is centralized in NYC. Each city has a Help Desk
department. The MIS staff utilizes the Help Desk staff when problems
arise.
6. The Sales department is in New York, Atlanta and San Diego.
7. The Marketing department is in Atlanta and San Diego.
8. Research is handled at the Kansas City office.
9. Accounting and Distribution is processed from Chicago.
10. Atlanta, Chicago, Kansas City and San Diego are all connected to
NY from a separate T1 line. In addition, Atlanta and Chicago have
their own T1 line. The company is looking to you to determine if the
current links should be updated and if additional links should be
purchased.
Based on the information above, evaluate the current network
infrastructure. Explain any updates to the current T1 network you feel
is necessary. Design an IP scheme that will minimize broadcast traffic
on the WAN links. Provide IP address ranges and your subnet mask in
your design. Propose how the routing tables on the Cisco routers will
be managed. Determine if you will use static or dynamic routes. Defend
your proposal. |
