Modifies the name, description, and enables or disables automatic route advertisement for a virtual border router (VBR) connection on an Enterprise Edition transit router.

Operation description

The UpdateTransitRouterVbrAttachmentAttribute operation is asynchronous. The system returns a RequestId, while continues running in the background. You can call the ListTransitRouterVbrAttachments operation to query the status of the VBR connection.

  • When the VBR connection is in the Modifying state, the VBR connection is being modified. You can only query VBR connections.

  • When the VBR connection is in the Attached state, the VBR connection is modified.

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.

boolean

No

Specifies whether to perform a dry run to check permissions and instance status. Valid values:

  • false (default): sends a normal request and modifies the name and description of the VBR connection.
