Tutorial: Configure both routing preference options for a virtual machine using the Azure portal

This article shows you how to configure both routing preference options (Internet and Microsoft global network) for a virtual machine (VM). This configuration is achieved using two virtual network interfaces. One network interface is configured with a public IP routed via the Microsoft global network. The other network interface is configured with a public IP routed via an ISP network.

In this tutorial, you learn how to:

• Create a virtual machine with a public IP address with the Microsoft network routing preference.
• Create a public IP address with the Internet routing preference.
• Create a secondary network interface for the virtual machine.
• Associate the Internet routing preference public IP to the virtual machine secondary network interface.
• Attach secondary network interface to virtual machine.

Prerequisites

• An Azure account with an active subscription. Create an account for free.
