This topic describes how to associate a Cloud Connect Network (CCN) instance with a transit router of Cloud Enterprise Network (CEN) in the same region. After you associate a CCN instance with a transit router, you can use the transit router to establish private network connections.
Background information
Transit routers provide Basic Edition and Enterprise Edition. Transit routers of Enterprise Edition provide a wider range of features to manage routes. For more information about transit routers of Basic Edition and Enterprise Edition, see How transit routers work.
Before you associate a CCN instance, take note of the following information:
CCN regions support only transit routers of Basic Edition.
You can associate a transit router of Basic Edition with a CCN instance that belongs to the same or another Alibaba Cloud account. If you want to associate a transit router with a CCN instance that belongs to another Alibaba Cloud account, you must first obtain authorization. For more information, see Grant permissions on a network instance that belongs to another 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 CEN details page, you can use one of the following methods to navigate to the Connection with Peer Network Instance page and create a network instance connection.
On the Basic Settings tab, click
next to CCN.
NoteIf no transit router is created for the CEN instance, you can use this method to create the first network instance connection.
On the Basic Settings>Transit Router tab, find a transit router and click Create Connection in the Actions column.
On the Connection with Peer Network Instance page, set the following parameters and click OK.
