vdc/Modules/VirtualNetwork/2.0

vNet

This template deploys a Virtual Network (vNet) with 2 optional Subnets.

Resources

• Microsoft.Network/virtualNetworks
• Microsoft.Network/virtualNetworks/subnet

Parameters

Parameter Name	Default Value	Description
vnetName		Required. The Virtual Network (vNet) Name.
vnetAddressPrefix		Required. An Array of 1 or more IP Address Prefixes for the Virtual Network.
subnets		Required. An Array of subnets to deploy to the Virtual Network.
ddosProtectionPlanResourceId	empty	Optional. The Resource Id of the DDoS Protection Plan.
enableDdosProtection	true	Optional. Indicates if DDoS protection is enabled for all the protected resources in the Virtual Network. A 'true' value requires a DDoS Protection Plan to be specified.
enableVmProtection	true	Optional. Indicates if VM protection is enabled for all the subnets in the Virtual Network.

Parameter Usage: vnetAddressPrefix

The vnetAddressPrefix parameter accepts a JSON Array of string values containing the IP Address Prefixes for the Virtual Network (vNet).

Here's an example of specifying a single Address Prefix:

"vnetAddressPrefix": {
    "value": [
        "10.1.0.0/16"
    ]
}

Parameter Usage: subnets

The subnets parameter accepts a JSON Array of subnet objects to deploy to the Virtual Network.

Here's an example of specifying a couple Subnets to deploy:

"subnets": {
    "value": [
    {
        "name": "app",
        "properties": {
        "addressPrefix": "10.1.0.0/24",
        "networkSecurityGroup": {
            "id": "[resourceId('Microsoft.Network/networkSecurityGroups', 'app-nsg')]"
        },
        "routeTable": {
            "id": "[resourceId('Microsoft.Network/routeTables', 'app-udr')]"
        }
        }
    },
    {
        "name": "data",
        "properties": {
        "addressPrefix": "10.1.1.0/24"
        }
    }
    ]
}

Outputs

Output Name	Description
vNetResourceGroup	The name of the Resource Group the Virtual Network was created in.
vNetResourceId	The Resource id of the Virtual Network deployed.
vNetName	The name of the Virtual Network deployed.
subnetNames	The Names of the Subnets deployed to the Virtual Network.
subnetIds	The Resource Ids of the Subnets deployed to the Virtual Network.

Considerations

When defining the Subnets to deploy using the subnets parameter, the JSON format to pass it must match the Subnet object that is normally passed in to the subnets property of a virtualNetwork within an ARM Template.
