This topic describes how to attach a VPC to a CEN instance. By using a CEN instance, you can establish a private channel between two VPCs or between a VPC and an on-premises data center to interconnect global cloud resources. You can attach a VPC to a CEN instance under the same account, or attach a VPC to a CEN instance under another account through cross-account authorization.

Attach a VPC to a CEN instance under the same account

You can attach a VPC to a CEN instance under the same account. By doing so, the VPC can communicate with other VPCs in the CEN instance or on-premises data centers. For more information, see Attach a VPC or VBR to a CEN instance through the instance details page.

Grant cross-account permissions to a CEN

You can attach a VPC to a CEN instance under another account after you grant permissions to the CEN. In this way, the VPC can communicate with the instances in the CEN. For more information, see Cross-account authorization.
