achieved with breakaways, but only if all routers have their inputs and outputs mapped 1:1. This is a simple
example of virtual routing. You can build up a complex map of several different physical devices that become one
virtual device. When a switch request is made for a virtual device, all the physical devices that are mapped to the
virtual device are switched.

When changes are made to the configuration of a device, the changes are not activated in the device until the
configuration file containing the changes is sent to the device. You can save a configuration file, but it will not be
loaded to the device until it is sent to the device. Once a configuration file has been sent to the device, the NK-VRC
operates transparently, mapping virtual switch requests from a remote control panel to physical switch requests for
the routing switchers.
