Specifying the Interface
OSPF divides the AS into different areas. You must configure each OSPF interface
to belong to a particular area, identified by an area ID. The areas transfer routing
information between them through the ABRs.
In addition, parameters of all the routers in the same area should be identical.
Therefore, when configuring the routers in the same area, please note that most
configurations should be based on the area. An incorrect configuration can disable
