Scenario 4-5: Recommendations for Designing OSPF Networks
This scenario presents some of the design recommendations found in common literature. This is not a practical scenario but rather a presentation of some design guidelines to help you in real-life network situations you might come across in designing today's complex IP networks.
By no means are these rules standard, and they are provided here for reference so you can easily refer to a sample network design and the common rules experts adhere to in large OSPF networks.
When architecting a network, you should try to accomplish five basic goals with dynamic routing protocols:
Functionality— The network works; that is, no matter what failure or scenario, the network must always be functioning. ...
