Aggregate Routes
Aggregate routes allow you to combine groups of routes with common addresses into a single entry. By combining
routes into a single entry, you can decrease the number of route advertisements sent by your device, thus
decreasing the size of the routing tables maintained by neighboring devices. A second advantage of advertising a
single route prefix that represents all other internal route prefixes is that internal routing instabilities can be hidden
from external peers.
