This topic describes how to allow network instances that are attached to a Cloud Enterprise Network (CEN) instance to communicate with each other. In this example, the network instances are virtual private clouds (VPCs), virtual border routers (VBRs) that are associated with data centers, and Cloud Connect Network (CCN) instances that are connected with headquarters or branches. The procedure varies based on the accounts and regions to which the network instances belong. Before you use CEN to connect network instances, take note of the accounts and regions to which the network instances belong.

The network instances are created by the same account and in the same region

If the network instances that you want to connect are created by the same account and in the same region, you can attach them to a CEN instance. This way, the attached network instances can communicate with each other.

Procedure:

The network instances are created by the same account but in different regions

If the network instances are created under the same account and in different regions, you must set the bandwidth for cross-region communication.

Procedure:

The network instances are created in the same region but by different accounts

If the network instances are created in the same region but by different accounts, you must acquire the permissions from the attached network instances. Then, you can attach the network instances to a CEN instance.
