2.4.4. Configuring the IPv6 Isolated Network

The default Heat template collection contains a Jinja2-based environment file for the default networking configuration. This file is environments/network-environment.j2.yaml. When rendered with our network_data file, it results in a standard YAML file called network-environment.yaml. Some parts of this file might require overrides, which is why you should create your own custom network-environment.yaml file. For this scenario, create a custom environment file (/home/stack/network-environment.yaml) with the following details:

parameter_defaults:
  DnsServers: ["8.8.8.8","8.8.4.4"]
  ControlPlaneDefaultRoute: 192.0.2.1
  ControlPlaneSubnetCidr: "24"
  EC2MetadataIp: 192.0.2.1

parameter_defaults:
  DnsServers: ["8.8.8.8","8.8.4.4"]
  ControlPlaneDefaultRoute: 192.0.2.1
  ControlPlaneSubnetCidr: "24"
  EC2MetadataIp: 192.0.2.1

The parameter_defaults section contains the customization for certain services that remain on IPv4.
