The ARM template er-gtw.json creates an Azure VNet with an ExpressRoute Gateway. The ExpressRoute Gateway can be deployed with/without zoning.
The network diagram is shown below:
The parameter ipZoning in ARM template is boolean:
- it returns a value true is the ExpressRoute Gateway is set with SKU in zoning: "ErGw1AZ", "ErGw2AZ", "ErGw3AZ".
- it returns a value false if the ExpressRoute Gateway SKU is set to one of values: "Standard", "HighPerformance", "UltraPerformance".
ExpressRoute Gateway in availability zone requires a single IP with Standard SKU and Static allocation method.
The variables in ARM template er-gtw.json:
"pubIPSKU": "[if(parameters('ipZoning'),'Standard','Basic')]",
"pubIPAllocationMethod": "[if(parameters('ipZoning'),'Static','Dynamic')]",assign the values in the public IP of the ExpressRoute Gateway:
{
"comments": "public IP of the ExpressRoute Gateway",
"type": "Microsoft.Network/publicIPAddresses",
"apiVersion": "2020-06-01",
"name": "[variables('gatewayPublicIPName')]",
"location": "[variables('location')]",
"sku": {
"name": "[variables('pubIPSKU')]"
},
"properties": {
"publicIPAllocationMethod": "[variables('pubIPAllocationMethod')]"
}
}
[!NOTE1] Before spinning up the ARM template you should change the following in the file er-gtw.json:
- variable $subscriptionName: name of your Azure subscription
[!NOTE2] Deployment of ExpressRoute Gateway in availability zone is supported only in Azure region with zoning.
