OSPF Area Settings
An OSPF domain is divided into areas that are labeled with 32-bit area identifiers which are
commonly written in the dot-decimal notation of an IPv4 address. Areas are used to divide a large
network into smaller network areas. They are logical groupings of hosts and networks, including
their routers having interfaces connected to any of the included networks. Each area maintains a
separate link state database whose information may be summarized towards the rest of the network
by the connecting router. Thus, the topology of an area is unknown outside of the area. This
reduces the amount of routing traffic between parts of an autonomous system.
