Cloud Enterprise Network:RoutePrivateZoneInCenToVpc

Last Updated:Oct 26, 2026

Configures the PrivateZone service.

Operation description

PrivateZone is a private DNS domain name resolution and management service based on the Alibaba Cloud Virtual Private Cloud (VPC) environment. After a Virtual Border Router (VBR) instance or a Cloud Connect Network (CCN) instance is attached to a Cloud Enterprise Network (CEN) instance, the associated on-premises networks can access the PrivateZone service through the CEN instance.

  • The on-premises networks associated with VBR and CCN instances can only access the PrivateZone service in the same region.

    For example, if the PrivateZone service is located in the China (Beijing) region, only the on-premises networks associated with VBR instances in the China (Beijing) region and CCN instances in the Chinese mainland can access the PrivateZone service.

  • The RoutePrivateZoneInCenToVpc operation is asynchronous. The system first returns a RequestId, but the PrivateZone service configuration is not yet complete, and the background task is still running. You can call the DescribeCenPrivateZoneRoutes operation to query the status of the PrivateZone service.

    • When the PrivateZone service is in the Creating state, the PrivateZone service configuration is being added. In this state, you can only query the PrivateZone service configuration and cannot perform other operations.

    • When the PrivateZone service is in the Active state, the PrivateZone service configuration is added.

    • When the PrivateZone service is in the Failed state, the PrivateZone service configuration fails to be added.

Before you begin

Before you invoke the RoutePrivateZoneInCenToVpc operation, make sure that the following conditions are met:

  • The PrivateZone service deployment is complete. For more information, see Quick start for PrivateZone DNS parse.

  • Make sure that you load the VPC-connected instance associated with the PrivateZone service, and the VBR or CCN instance in the access region to the same CEN instance. For more information, see AttachCenChildInstance.

  • If your on-premises network is connected to Alibaba Cloud by using a CCN instance, and the account to which the CCN instance belongs is different from the account to which the VPC-connected instance or the CEN instance belongs, you must first complete the authorization for the CCN instance. For more information, see Authorize a Cloud Connect Network.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
