This topic describes how to use a Cloud Enterprise Network (CEN) to interconnect network instances, such as VPCs, VBRs associated with on-premises data centers, and CCNs to which local branches or headquarters is added. The procedure varies depending on the specific regions and accounts. Before using a CEN to configure network interconnection, you must specify the accounts and regions of the networks.

Interconnect network instances under the same account in the same region

To interconnect network instances under the same account in the same region, you need to attach these network instances to a CEN instance.

Interconnect network instances under the same account in different regions

To interconnect network instances under the same account in different regions, you need to attach these network instances to a CEN instance and set a cross-region connection bandwidth.
