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.
