CreateVcoRouteEntry - Virtual Private Cloud - Alibaba Cloud Documentation Center

Adds a destination-based route for an IPsec-VPN connection.

Operation description

The IPsec-VPN connection must be associated with a transit router. For more information, see CreateTransitRouterVpnAttachment .
You cannot create a destination-based route whose destination CIDR block is 0.0.0.0/0.
Do not add a destination-based route whose destination CIDR block is 100.64.0.0/10, or a CIDR block that contains 100.64.0.0/10 or belongs to 100.64.0.0/10. Such a route will make the console fail to display the status of the IPsec-VPN connection or cause IPsec negotiation failures.
CreateVcoRouteEntry 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 DescribeVpnConnection to query the status of the task.
- If the IPsec-VPN connection is in the updating state, the destination-based route is being created.
- If the IPsec-VPN connection is in the attached state, the destination-based route is created.
You cannot repeatedly call CreateVcoRouteEntry within the specified period of 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.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

RouteDest	string	Yes	The destination CIDR block of the destination-based route.	192.168.10.0/24
Weight	integer	Yes	The weight of the destination-based route. Valid values: 0: a low priority 100: a high priority	100
NextHop	string	Yes	The next hop of the destination-based route.	vco-p0w2jpkhi2eeop6q6****
Description	string	No	The description of the destination-based route.	desctest
OverlayMode	string	No	The tunneling protocol. Set the value to Ipsec, which specifies the IPsec tunneling protocol.	Ipsec
ClientToken	string	No	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.	123e4567-e89b-12d3-a456-4266****
