A Quick Explanation of Areas in OSPF Networks

Using the OSPF (open shortest path first) IGP (interior gateway protocol) within a software-defined network can have many advantages. Though, there are still many advanced configuration options that network administrators need to understand. One of those configuration options is dividing the network into areas.

OSPF networks can be divided into multiple sub-domains. These sub-domains are called areas. An area is a logical collection, or grouping, of existing OSPF networks, routers, and links. These collection items share the same area identification.

One of the advantages of dividing an OSPF network into areas is reducing the link-state database. Elements within an area cannot view or understand the topology of the network outside of its defined area. This reduces the database size that each router must maintain for link-states. Likewise, each router must be synchronized and be the same. Network admins can configure route summarization and filtering between different areas, though.
