By associating a Virtual Private Cloud (VPC) with a Global Direct Exchange Gateway (DXGW), you can enable private network connectivity between your on-premises data center (IDC) and VPC.

Prerequisites

You have created a DXGW instance. If not, see Creating a Global Direct Exchange Gateway.

You have created a VPC instance. This VPC is not been associated with any DXGW. If not, see Creating a VPC.

Procedure

Click the name of the target DXGW and select the Virtual Private Cloud tab.

Click Associate VPC.

Configure parameters based on the table below.

Parameter	Description	Example
Resource owner	Currently, only supports VPC instances within the same account.	Same-account
Region	Select the region where the VPC is deployed.	China (Beijing)
VPC	Select the VPC instance.	vpc-30wq9gu***
Allowed route prefix	A route prefix is the CIDR block used to match route entry traffic. Both IPv4 and IPv6 route prefixes are supported. Before configuration: DXGW forwards all CIDR routes from the VPC to the IDC. After configuration: DXGW forwards only routes matching the specified route prefixes to the IDC. tip Route prefix configurations must not overlap for VPCs associated with the same DXGW. In complex hybrid cloud networking scenarios, the route prefix you set has the highest forwarding priority. For other priority rules, see Feature Limits.	10.XX.XX.0/24

Click OK to complete the action.

Modify VPC configuration: After associating a VPC with DXGW, you can modify the route prefix and configure specific route propagation as needed.

Disassociate VPC: DXGW supports associating multiple VPCs. You can also disassociate a VPC as needed.
