To allow a data center connected to a Cloud Connect Network (CCN) instance to communicate with other networks that are connected to a transit router, such as virtual private clouds (VPCs) in the same region or in a different region, connect the CCN instance to the transit router.
Prerequisites
A transit router is deployed in the region of the CCN instance. For more information, see Create a transit router.
Transit routers can be connected to CCN instances that belong to the same Alibaba Cloud account or a different Alibaba Cloud account. If the CCN instance and the transit router belong to different Alibaba Cloud accounts, grant the required permissions to the CCN instance. For more information, see Grant a transit router permissions on a network instance that belongs to another Alibaba Cloud account.
Procedure
Log on to the CEN console.
On the Instances page, click the ID of the CEN instance that you want to manage.
On the tab, find the transit router that you want to manage and click Create Connection in the Actions column.
On the Connection with Peer Network Instance page, set the following parameters and click OK.
Parameter
Description
Network Type
Select Cloud Connect Network (CCN).
Region
Select the region where the network instance is deployed.
Transit Router
The transit router in the selected region is displayed.
Resource Owner ID
Select the Alibaba Cloud account that owns the network instance.
If the network instance and the transit router that you want to connect belong to the same Alibaba Cloud account, select Current Account.
If the network instance and the transit router that you want to connect belong to different Alibaba Cloud accounts, select Different Account, and enter the ID of the Alibaba Cloud account to which the network instance belongs.
Network Instance
Select the ID of the CCN instance that you want to connect to the transit router.
After you connect a CCN instance to a transit router, the CCN instance automatically advertises routes to the route tables of the transit router.
After you create a CCN connection, you can view the details about the CCN connection on the Intra-region Connections tab on the details page of the transit router. For more information, see View network instance connections.
