Redundant Gateway is a Ring redundancy feature that you can implement for backup if two links fail in a
Ring.
In the images above, the Redundant Ring, IP:192.168.11.1 is the main gateway, and there are other devices in
the same ring which provides a Cellular interface for external network transmission.
If there are two link failures, this would mean that the other devices cannot transmit data to the external
network. You would manually need to change the settings on each device to recover external access.
To solve this problem, you can use the
Redundant Gateway
. If two links fail, the Redundant Gateway device
creates an internal virtual gateway (the same as original main gateway) so for other devices, the main
gateway still exists and these devices can transmit data to external network via Cellular interface of the
Redundant Gateway device.
