OSPF Global Settings
Each L3 switch/router has an OSPF router ID, customarily written in the dotted decimal format (e.g., 1.2.3.4)
of an IP address. This ID must be established in every OSPF instance. If not explicitly configured, the default ID
(0.0.0.0) will be regarded as the router ID. Since the router ID is an IP address, it does not have to be a part
of any routable subnet in the network.

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.
