Network appliance to monitor primary and secondary internet links and automatically enable ports of other devices connected to the secondary router?

Is there a network appliance that can monitor primary and secondary internet links/circuits and if the primary link/circuit were to go down, this network device can automatically enable ports on devices connected to secondary internet link/circuit that have duplicated IP settings of the primary router's devices? And subsequently shut down the ports on devices connected to the secondary internet link/circuit when the primary internet link/circuit comes back online. The ports of devices connected to the secondary internet link/circuit should always remain disabled while the primary internet link/circuit is active and working because those devices' ports will have duplicated settings of the primary router's devices and should only be activated by the network appliance when the primary internet circuit goes down.

What you describe is called a network failover / fallback switch.  They are made by numerous manufacturers.  It is not a commonly used item -- certainly not on the order of routers or firewalls -- so expect to pay more for it than other comparable network equipment.
