1. Let's go ahead and create an isolated network and name it private, as follows:

- name: creating a private network
  os_network:
    state: present
    name: private

2. In the preceding example, we created a logical network with no subnets. A network with no subnets is of little use, so the next step would be to create a subnet:

- name: creating a private subnet
  os_subnet:
    state: present
    network_name: private
    name: app
    cidr: 192.168.0.0/24
    dns_nameservers:
      - 8.8.4.4
      - 8.8.8.8
    host_routes:
      - destination: 0.0.0.0/0
        nexthop: 104.131.86.234
      - destination: 192.168.0.0/24
        nexthop: 192.168.0.1
