Tutorial: Create an Azure Virtual WAN hub

Before you begin, ensure you have the following:

• An Azure subscription. If you don't have one, create a free account before you begin.
• You can deploy Virtual WAN resources in any region, but the hub will be deployed in the selected region.

Steps

1. In the Azure portal, search for and select Virtual WANs.

2. On the Virtual WANs page, select + Create.

   • Name: Enter a name for your virtual hub (e.g., MyHub).
   • Hub private address space: Enter a CIDR block for the hub's address space (e.g., 10.0.0.0/24). This space should not overlap with any connected networks.
   • Virtual hub capacity: Select the capacity based on your throughput requirements.
   • Hub routing preference: Select Azure for Azure routing or None if you plan to use a network virtual appliance (NVA) for routing.

5. Select Review + create, then select Create.

You have successfully created a Virtual WAN and a virtual hub. The next steps typically involve:

• Connecting your sites (e.g., VPN sites, ExpressRoute circuits) to the virtual hub.
• Deploying network virtual appliances (NVAs) for advanced routing or security.
• Configuring routing policies to control traffic flow.
