Azure ExpressRoute Circuit Peerings

Manage and configure connectivity for your Azure ExpressRoute circuits.

ExpressRoute Circuit Peerings

Overview

ExpressRoute circuit peerings enable private connectivity between your on-premises network, Microsoft 365, or Azure services. Each ExpressRoute circuit can have up to three peerings: Azure Public, Azure Private, and Microsoft 365.

Peerings are configured at the circuit level and associate routing information with specific network types. You can manage the peerings for a selected ExpressRoute circuit here.
