Virtual Private Cloud:ModifyVpnRouteEntryWeight

Last Updated:Dec 02, 2023

Modifies the weight of a destination-based route of a VPN gateway.

Operation Description

  • ModifyVpnRouteEntryWeight is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call DescribeVpnGateway to query the status of the task.

    • If the VPN gateway is in the updating state, the weight of the destination-based route is being modified.
    • If the VPN gateway is in the active state, the weight of the destination-based route is modified.
  • You cannot repeatedly call the ModifyVpnRouteEntryWeight operation to modify the weight of destination-based route for the same VPN gateway within the specified period of time.


You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Request parameters


The ID of the region where the VPN gateway is created. You can call the DescribeRegions operation to query the most recent region list.


The client token that is used to ensure the idempotence of the request.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters.

Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

The ID of the VPN gateway.


The destination CIDR block of the destination-based route.

The next hop of the destination-based route.


The previous weight of the destination-based route. Valid values:

  • 0: a low priority
  • 100: a high priority

The new weight that you want to set for the destination-based route. Valid values:

  • 0: a low priority
  • 100: a high priority

The tunneling protocol. Set the value to Ipsec.


Response parameters


The request ID.
