-# Defines Network Environment for a Baremetal Deployment
-# Any values missing will be auto-detected on the jumphost
+# This configuration file defines Network Environment for a
+# Baremetal Deployment of OPNFV. It contains default values
+# for 4 following networks:
+#
+# - admin
+# - private*
+# - public
+# - storage*
+#
+# *) optional networks
+#
+# Any values missing from this configuration file will be
+# auto-detected by deployment script from the existing network
+# configuration of the jumphost.
+#
+# Optional networks will be consolidated with the admin network
+# if not explicitely configured.
+#
+# See short description of the networks in the comments below.
+#
+
+# "admin" is the short name for Control Plane Network.
+# During OPNFV deployment it is used for node provisioning so
+# PXE boot should be enabled for the related interfaces on all
+# the nodes in the OPNFV cluster. After the deployment this
+# network is used as the OpenStack management network which
+# carries e.g. communication between its internal components.
