Gateway redundancy is a network design approach that uses two or more gateways to maintain connectivity when one gateway becomes unavailable. Instead of relying on a single gateway, systems can switch to another available gateway if the primary one fails. This helps reduce interruptions and keeps devices, applications, and networks connected during hardware failures or maintenance.
It is commonly used in business networks, data centers, cloud environments, and other systems where continuous connectivity is important. Redundant gateways can operate in an active-standby arrangement, where one handles traffic while another waits to take over, or through other failover configurations. By providing an alternative communication path, gateway redundancy improves network availability, supports reliable operations, and reduces the impact of unexpected gateway failures.
