OSPF Design: 3 – Fundamentals

OSPF benefits
  • Fast convergence
  • Variable-length subnet masking (VLSM)
  • Authentication
  • Hierarchical segmentation
  • Route summarization
  • Aggregation

Routing Summarization is a major factor in the success of designing your network. To ensure that your network can scale properly, route summarization is the biggest factor against which to measure your success. Without summarization, you have a flat address design with specific route information for every subnet being transmitted across the network—a bad thing in large networks.

Route Summarization - Network Stability

The six time-proven steps to designing a network are as follows:

  1. Analyze the requirements.
  2. Develop the network topology.
  3. Determine the addressing and naming conventions.
  4. Provision the hardware.
  5. Deploy protocol and Cisco IOS Software features.
  6. Implement, monitor, and maintain the network.

Consider the following issues when working through the network design process: Continue reading “OSPF Design: 3 – Fundamentals”
