Benefits of a Hierarchical Network There are many benefits associated with hierarchical network designs. Scalability Hierarchical networks scale very well. The modularity of the design allows you to replicate design elements as the network grows. Because each instance of the module is consistent‚ expansion is easy to plan and implement. For example‚ if your design model consists of two distribution layer switches for every 10 access layer switches‚ you can continue to add access layer switches
