VPN Gateway:ModifyVcoRouteEntryWeight

Last Updated:Sep 01, 2026

Modifies the weight of a destination-based route for an IPsec-VPN connection.

Operation description

  • ModifyVcoRouteEntryWeight 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 DescribeVpnConnection operation to query the status of the IPsec-VPN connection and check whether the weight of the destination-based route is modified.

    • If the IPsec-VPN connection is in the updating state, the weight of the destination-based route is being modified.

    • If the IPsec-VPN connection is in the attached state, the weight of the destination-based route is modified.

  • Do not repeatedly call the ModifyVcoRouteEntryWeight operation on the same IPsec-VPN connection within a short period of time.
