    Cloud Enterprise Network:CreateCenChildInstanceRouteEntryToAttachment

    Last Updated:Mar 25, 2024

    Adds a route entry to a network instance and sets the next hop of the destination CIDR block to the transit router in the current region.

    Operation description

    • You can add routes only to virtual private clouds (VPCs) or virtual border routers (VBRs) that are connected to an Enterprise Edition transit router.

    • By default, the next hop of the routes is the transit router connection, which is the connection between the VBR and the Enterprise Edition transit router. You cannot modify the next hop.

    • CreateCenChildInstanceRouteEntryToAttachment is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the DescribeRouteEntryList operation to query the status of a route.

      • If a route is in the Pending state, the route is being created. You can query the route but cannot perform other operations.
      • If a route is in the Available state, the route is created.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
