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 to another Alibaba Cloud account.

Procedure

  1. Log on to CEN console.
  2. On the Instances page, find the CEN instance that you want to manage and click its ID.
  3. 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 Add next to CCN.
      Note If 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.
  4. 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 created.
    Transit Router Displays transit routers that are created in the selected region.

    If no transit router is found in the selected region, the system automatically creates a transit router.

    Resource Owner ID Select the type of account to which the network instance that you want to connect belongs.
    • If the network instance that you want to connect and the CEN instance belong to the same account, select Your Account.
    • If the network instance that you want to connect and the transit router belong to different accounts, select Different Account and enter the ID of the network instance owner.
    Networks Select the ID of the CCN instance to be associated.

    After you associate a CCN instance with a transit router, the CCN instance automatically advertises routes to the route table of the transit router.
