Overview
Provides details about practical scenarios where a centralized architecture meets specific organizational needs. Reviewing these examples, such as implementing centralized firewall services for branch traffic, helps you identify opportunities to enhance security and policy enforcement across your network locations.
Hub-and-spoke use cases describe practical scenarios where this network topology is effectively applied to meet specific organizational needs and leverage its benefits.
Example (Centralized Network Services)
Consider an organization's network with the following characteristics:
-
Headquarters Site: Features a single device designated as a hub, running numerous network services such as an enterprise firewall.
-
Branch Sites: Consists of three branch locations, each equipped with an edge router.
Network administrators choose to implement a hub-and-spoke topology to route all traffic between branch sites through the headquarters hub. This strategic decision allows for the consistent application of centralized network services to all inter-branch traffic, enhancing security and policy enforcement.
The following illustration depicts the configured hub-and-spoke topology for this use case.
