The /etc/inet/ike/config file is extended by Trusted Extensions to
include label information. The ike.config(5) man page describes the label_aware global parameter and three Phase 1 transform parameters, single_label and multi_label, and wire_label.
Note - The IKE configuration file contains a keyword, label,
that is used to make a Phase 1 IKE rule unique. The IKE keyword label is
distinct from Trusted Extensions labels.
