Overview
Scenario
Direct Connect establishes a dedicated, secure, stable, and high-speed network connection between your on-premises data center and VPCs. Direct Connect now provides global DC gateways that allow you to build a large-scale hybrid cloud network globally.
Enterprise Router helps choose the fastest possible route dynamically and switch between Direct Connect connections. It balances the load among connections and fully uses the network bandwidth. This makes network transmission faster, more reliable, and better performing.
In this practice, an enterprise router and a global DC gateway are used together to allow an on-premises data center to access the VPCs.
Architecture
Suppose your enterprise has deployed two VPCs in a region. The two VPCs need to communicate with each other and communicate with your on-premises data center through a global DC gateway.
For this to work, you can create an enterprise router in the region and attach the VPCs and the global DC gateway to the enterprise router. The enterprise router can forward traffic between the VPCs and the global DC gateway.
Constraints
The subnet CIDR blocks of the VPCs and of the on-premises data center cannot overlap.
