The minimum label and maximum label attributes are used to establish the label range for labeled and unlabeled hosts. These attributes are used to do the following:
To set the label range that can be used when a host communicates with a remote labeled host
In order for a packet to be sent to a destination host, the label of the packet must be within the label range assigned in the destination host's security template.
To set a label range for packets that are being forwarded through a labeled gateway or an unlabeled gateway
The label range can be specified in the template for an unlabeled host type. The label range enables the host to forward packets that are not necessarily at the label of the host, but are within a specified label range.
