- During the installation process of the gateway, you can proceed and install the ExpressRoute circuit. To do so: You need to go back to your Resource group and click Add again. From the marketplace, we select the ExpressRoute:
- In the next blade, we set up our ExpressRoute circuit. Now we need the information your ISP gave you:
-
- Circuit name: The name of your ExpressRoute circuit.
- Provider: The provider you or your ISP uses for the peering with Microsoft Azure.
- Peering location: The edge gateway location your provider peers with Microsoft.
- Bandwidth: The bandwidth you ordered from your ISP.
- SKU: Select the service level for your ExpressRoute.
- Billing model: Select your billing. With Metered you will pay per download. With Unlimited you have a flat rate for your network traffic.
- Allow classic operations: Enables your Azure Service Manager deployment model environment to use the ExpressRoute too.
Please be aware that the billing for your Azure ExpressRoute will start as soon as you click Create. To reduce unnecessary deployment costs, you should do that together with your service provider during a live activation session for both sites of the service.
- After you have created the ExpressRoute circuit, you need to provide the Service key to your provider. The Service key will identify your Azure Subscription against its deployment and it can then create the connection to your environment.
- You can find the Service key within the settings of the ExpressRoute circuit after it is completely deployed:
- After the Provider status has changed to Provisioned, you can configure the Azure peering's:
- To configure the peering's in Azure, you need additional information from your ISP. You need the Peer ASN, Primary subnet, Secondary subnet, VLAN ID, and for Microsoft peering, the Advertised public prefixes:
- To configure the peering, click on the peering type you want to configure:
- Within the upcoming blade, you configure the information you've got from your ISP:
- In Azure you don't need to do additional routing. As soon as you establish the connection, Azure will directly configure the BGP settings.
- After you have configured the peering's, you need to create a connection between the ExpressRoute circuit and the Azure virtual network gateway, like you already did for VPN in the previous guide.
