The Minimum Label and the Maximum Label are used in the following ways:
To set the range of labels that can be used when communicating with a computer.
In order for a packet to be sent to a computer, the label of the packet must be within the label range assigned to the destination computer in its template.
To set a label range for packets being forwarded through an unlabeled or RIPSO gateway.
The label range can be specified in the template for an unlabeled or RIPSO host type to make it possible to forward a packet to that computer for forwarding, even when the packet's label is not the same as the Default Label.
