Route aggregation offers several advantages, including the following:
* reduces the number of entries in the route table, which reduces the load on the router and network overhead for routing protocols;
* minimizes latency in a complex network, especially when many routers are involved;
* reduces or eliminates unnecessary routing updates after part of the network undergoes a change in CPU cycles topology;
* hides instability in the system behind the summary that remains valid even in the absence of summarized networks;
* saves memory since routing tables will be smaller in size;
* helps save bandwidth as there are fewer routes to advertise; and
* reduces processor workloads and saves, since there are fewer packets to process and smaller routing tables to work on.
