+There are assumptions in the demonstration VNF Heat templates about the
+networking available in the environment. To get the most value out of these
+templates and the automation that can help confirm the setup is correct, please
+observe the following constraints.
+
+
+``openStackPublicNetId:``
+ This network should allow Heat templates to add interfaces.
+ This need not be an external network, floating IPs can be assigned to the
+ ports on the VMs that are created by the heat template but its important that
+ neutron allow ports to be created on them.
+
+``openStackPrivateNetCidr: "10.0.0.0/16"``
+ This ip address block is used to assign OA&M addresses on VNFs to allow ONAP
+ connectivity. The demonstration Heat templates assume that 10.0 prefix can be
+ used by the VNFs and the demonstration ip addressing plan embodied in the
+ preload template prevent conflicts when instantiating the various VNFs. If
+ you need to change this, you will need to modify the preload data in the
+ Robot Helm chart like integration_preload_parameters.py and the
+ demo/heat/preload_data in the Robot container. The size of the CIDR should
+ be sufficient for ONAP and the VMs you expect to create.
+
+``openStackOamNetworkCidrPrefix: "10.0"``
+ This ip prefix mush match the openStackPrivateNetCidr and is a helper
+ variable to some of the Robot scripts for demonstration. A production
+ deployment need not worry about this setting but for the demonstration VNFs
+ the ip asssignment strategy assumes 10.0 ip prefix.
