Stub Network

Examples of stub networks include:

• An individual or group that uses only one router to link to an Internet service provider (ISP) (The individual/group are considered stub networks by the ISP.)
• One LAN that never carries multiple router data packets. Data traffic is always to or from local hosts.
• An enterprise-level LAN connected to a corporate intranet via one router or multiple routers connected to one logical destination
• An open-shortest-path-first (OSPF) area with one default OSPF routing domain path (The area may have multiple routers that know of only one default exit route.)

A good stub network analogy is an island that relies on a bridge as the sole mode of transportation to the mainland. Or, there may be multiple bridges, but each bridge only leads to a single point on the mainland.
