Terminology:
- Route summarization - Also known as prefix aggregation, routes are summarized into a single route to help reduce the size of routing tables. For instance, one summary static route can replace several specific static route statements.
- Supernetting - Occurs when the route summarization mask is a smaller value than the default traditional classful mask. It means that the supernet IP range overlaps with more then one Classfull network.
NB. A supernet is always a route summary, but a route summary is not always a supernet.
