Jinja2 loops

We can also loop through a list as well as a dictionary in Jinja2. We will use both as loops in nxos.j2:

    {% for vlan_num in item.value.vlans %}
    vlan {{ vlan_num }}
    {% endfor %}

    {% for vlan_interface in item.value.vlan_interfaces %}
    interface {{ vlan_interface.int_num }}
      ip address {{ vlan_interface.ip }}/24
    {% endfor %}

Provide the additional list and dictionary variables in the chapter8_8.yml playbook:

   vars:
     nexus_devices: {
       "nx-osv-1": {
       "hostname": "nx-osv-1",
       "username": "cisco",
       "password": "cisco",
       "vlans": [100, 200, 300],
       "vlan_interfaces": [
          {"int_num": "100", "ip": "192.168.10.1"},
          {"int_num": "200", "ip": "192.168.20.1"},
          {"int_num": "300", "ip": "192.168.30.1"}
        ]
       }
     }

Run the playbook, and you will see the configuration for both vlan and vlan_interfaces filled in on the router config.
