How to Configure an ExpressRoute

ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection with the help of a connectivity provider. With ExpressRoute, you can establish connections to Microsoft cloud services such as Microsoft Azure and Microsoft 365.

Note that you cannot create an ExpressRoute on a stand-alone site.

Before You Begin
