ACME case study

Case Study

Assignment:

Design IP addressing scheme and setup the network of the Acme Company. The IP addressing scheme must be able to support a minimum of 100 sites in each region but should be able to handle growth as the company expands into new markets. There are three regions. In each region there are a data center, two offices and two sites.

Requirements from Acme management:

All networks will be part of OSPF area 0
Each data center needs to supports 1,000 servers
Each office needs to support 50 workstations.
Each site will have up to 100 workstations and 10 servers.
A site will have serial link to each office in the region. 1 1544 kbps link to a primary office and a 64 kbps backup link to a secondary office.
Each router needs to have the following:
1. Enable, console, and VTY passwords.
2. Message of the day banner
3. All interfaces must have a description.

IP address ranges:

Link from West to Central 10.0.0.0/30
Link from Central to East 10.0.0.4/30
Link from West to East 10.0.0.8/30
West 10.64.0.0/10
Central 10.128.0.0./10
East 10.192.0.0/10

Plan & Configuration for Acme Network

Inter-DC Region

Inter-DC IP Scheme & Topology Map

IP addresses 10.0.0.12 to 10.63.255.255 are still available for future growth or for another region.

West Region

West Region IP Scheme & Topology Map

Each LAN allows for doubling or more of current IP address requirements.

IP addresses 10.64.11.88 to 10.127.255.255 are still available for future growth or for another region.
