aws ec2 modify-vpn-connection
Modifies the customer gateway or the target gateway of an AWS Site-to-Site VPN connection. To modify the target gateway, the following migration options are available: An existing virtual private gateway to a new virtual private gateway An existing virtual private gateway to a transit gateway An existing transit gateway to a new transit gateway An existing transit gateway to a virtual private gateway Before you perform the migration to the new gateway, you must configure the new gateway. Use CreateVpnGateway to create a virtual private gateway, or CreateTransitGateway to create a transit gateway. This step is required when you migrate from a virtual private gateway with static routes to a transit gateway. You must delete the static routes before you migrate to the new gateway. Keep a copy of the static route before you delete it. You will need to add back these routes to the transit gateway after the VPN connection migration is complete. After you migrate to the new gateway, you might need to modify your VPC route table. Use CreateRoute and DeleteRoute to make the changes described in VPN Gateway Target Modification Required VPC Route Table Updates in the AWS Site-to-Site VPN User Guide. When the new gateway is a transit gateway, modify the transit gateway route table to allow traffic between the VPC and the AWS Site-to-Site VPN connection. Use CreateTransitGatewayRoute to add the routes. If you deleted VPN static routes, you must add the static routes to the transit gateway route table. After you perform this operation, the AWS VPN endpoint's IP addresses on the AWS side and the tunnel options remain intact. Your AWS Site-to-Site VPN connection will be temporarily unavailable for a brief period while we provision the new endpoints
Options
| Name | Description |
|---|---|
--vpn-connection-id <string> | The ID of the VPN connection |
--transit-gateway-id <string> | The ID of the transit gateway |
--customer-gateway-id <string> | The ID of the customer gateway at your end of the VPN connection |
--vpn-gateway-id <string> | The ID of the virtual private gateway at the AWS side of the VPN connection |
--dry-run | Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation |
--no-dry-run | Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation |
--cli-input-json <string> | Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--generate-cli-skeleton <string> | Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command |
