What is high availability?
High availability allows you to configure multiple TWG-431BR routers to backup routers
as fault tolerance in case the primary router fails. The TWG-431BR 1 master and 5
standby in a high availability cluster.
In the example below, we will use 2 TWG-431BR routers in a high availability cluster.
Both router LAN interfaces are connected to the same LAN side switch. Assuming both
routers have different WAN IP Internet connections possibly to the same ISP or different
ISPs, the example below will explain how to configure LAN side High Availability.

them to the network.
