What is ExpressRoute Global Reach?

With ExpressRoute Global Reach, you can link ExpressRoute circuits together to make a private network between your on-premises networks.

You can enable ExpressRoute Global Reach to exchange data across your on-premises sites by connecting your ExpressRoute circuits. For example, if you have a private data center in California connected to an ExpressRoute circuit in Silicon Valley and another private data center in Texas connected to an ExpressRoute circuit in Dallas. With ExpressRoute Global Reach, you can connect your private data centers together through these two ExpressRoute circuits. Your cross data-center traffic will traverse through the Microsoft network.

ExpressRoute Global Reach is designed to complement your service provider’s WAN implementation and connect your branch offices across the world. For example, if your service provider primarily operates in the United States and has linked all of your branches in the U.S., but the service provider doesn’t operate in Japan and Hong Kong, with ExpressRoute Global Reach you can work with a local service provider and Microsoft will connect your branches there to the ones in the U.S. using ExpressRoute and our global network.
