Cloud Enterprise Network:RefreshTransitRouteTableAggregation

Last Updated:Aug 07, 2025

Re-advertises an aggregate route.

Operation description

For aggregate routes that failed to be advertised or were partially advertised, fix the route issue and call the RefreshTransitRouteTableAggregation operation to re-advertise the aggregate routes to virtual private clouds (VPCs). If you use the following solutions, the aggregate route is automatically advertised without manual operations:

  • Delete associated forwarding correlations

  • Disable route synchronization

  • Delete the VPC route table

  • Delete the aggregate route

You can call the DescribeTransitRouteTableAggregationDetail operation to view the advertisement status of the aggregate route.

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

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 support 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.
