Overview
Explains how to streamline your network topology by establishing a centralized communication model without complex control policies. Learn to designate routers as hubs or spokes to optimize resource demands and enforce centralized security services across the overlay network.
Hub-and-spoke topology configuration refers to a simplified method for setting up a hub-and-spoke network, particularly within a Cisco Catalyst SD-WAN. This configuration approach streamlines the process by eliminating the need for complex centralized control policies, which were traditionally required and often lengthy.
Feature history for Hub-and-Spoke
Lists the development milestones and release information for Hub-and-Spoke, including feature description.
Hub-and-Spoke configuration
Explains the simplified method for building a centralized architecture using transport gateway functionality and site-type attributes. Understanding this mechanism allows you to implement a hub-and-spoke topology that automatically filters route information to spokes, ensuring all inter-spoke traffic flows through a designated hub.
Hub-and-Spoke connectivity example
Provides details about the changes in network connectivity when converting a full-mesh environment into a centralized architecture. Reviewing this scenario helps you visualize how BFD sessions and route advertisements are modified to ensure that spokes communicate exclusively through the designated hub router.
Hub-and-Spoke use cases
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.
Configure a Hub-and-Spoke topology
Explains how to implement a centralized network model by enabling specific controller settings and assigning router roles. This task guides you through configuring transport gateways and defining site types to achieve an organized topology that simplifies management and reduces peer requirements.
Hub-and-Spoke configuration verification
Explains how to confirm that your centralized topology is operational and follows expected network behavior. This task involves using specific show commands to examine BFD sessions and OMP routes, ensuring that traffic is correctly following the designated hub-and-spoke paths.
