CreateVpnConnection - Virtual Private Cloud - Alibaba Cloud Documentation Center

Creates an IPsec-VPN connection.

Operation description

If the VPN gateway supports the dual-tunnel mode, you can specify the following parameters in addition to the required parameters when you call CreateVpnConnection:

ClientToken, Name, EffectImmediately, AutoConfigRoute, Tags array, TunnelOptionsSpecification array, and EnableTunnelsBgp.

For more information about the regions and zones that support the dual-tunnel mode, see IPsec-VPN connections support the dual-tunnel mode.
If the VPN gateway supports only the dual-tunnel mode, you can specify the following parameters in addition to the required parameters when you call CreateVpnConnection:

ClientToken, CustomerGatewayId, Name, EffectImmediately, IkeConfig, IpsecConfig, HealthCheckConfig, AutoConfigRoute, EnableDpd, EnableNatTraversal, BgpConfig, RemoteCaCertificate, and Tags array.
CreateVpnConnection 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 IPsec-VPN connection is being created.
- If the VPN gateway is in the active state, the IPsec-VPN connection is created.
You cannot call CreateVpnConnection to create multiple IPsec-VPN connections associated with a VPN gateway at the same time.

Debugging

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.
