Answer to the Question
When we use hierarchical addresing scheme, it helps us to perform Route Summarization. Route summarization is a technique which can be used to reduce the size of the Routing Table. It is a technique that is used to group IP networks together to minimize advertisements.It hides the details to simplify the routing process and it reduces router resource consumption (CPU and memory) required to store and process routes by reducing the number of routes.
