+## Configure ExpressRoute FastPath 
+You can enable [ExpressRoute FastPath](expressroute-about-virtual-network-gateways.md) if your ExpressRoute circuit is on [ExpressRoute Direct](expressroute-erdirect-about.md) and your virtual newtork gateway is Ultra Performance or ErGw3AZ. FastPath improves data path preformance such as packets per second and connections per second between your on-premises network and your virtual network. 
+
+> [!NOTE] 
+> If you already have a virtual network connection but haven't enabled FastPath you need to delete the virtual network connection and create a new one.
