Class OSPF_Area

  drcl.inet.protocol.ospf.OSPF_Area

public class OSPF_Area

extends java.lang.Object

The area data structure contains all the information used to run the basic OSPF routing algorithm. Each area maintains its own link-state database. A network belongs to a single area, and a router interface connects to a single area. Each router adjacency also belongs to a single area.

The OSPF backbone is the special OSPF area responsible for disseminating inter-area routing information.

The area link-state database consists of the collection of router-LSAs, network-LSAs and summary-LSAs that have originated from the area's routers. This information is flooded throughout a single area only.

The list of AS-external-LSAs (see Section 5) is also considered to be part of each area's link-state database.
