Which is a typical use case for hub-and-spoke WAN design?

The most common hub-and-spoke WAN design is the way an Internet service provider (ISP) is connected to its customers. The Internet connection is centrally located in a common physical location of the Internet provider called the point of presence or meet-me room. All lines connect out from this point in a hub-and-spoke design. Connections for an enterprise spread over a metropolitan area can connect in a number of different topologies, depending on what is available. Connections between two or more corporate locations are often a point-to-point or point-to-multipoint topology. An internal connection inside of a service provider's network can be made a number of ways using several different topologies.
