Flat Network Characteristics
- A flat network has no hierarchy or layers, and all devices operate on the same broadcast domain.
- It works for very small setups but lacks scalability and creates security problems as it grows.
Hierarchical Network Benefits
- Hierarchical network models separate layers into access, aggregation, and core to manage scale and traffic flow.
- The aggregation layer helps in scaling and can centralize security policies.
Use Aggregation for Security
- Use the aggregation layer to apply security enforcement and reduce complexity in core switches.
- Multi-home switches for redundancy to prevent single points of failure in critical links.
