CreateVpnPbrRouteEntry - Virtual Private Cloud - Alibaba Cloud Documentation Center

Creates a policy-based route for a VPN gateway.

Operation description

Before you call this operation, make sure that you are familiar with the match rules of and limits on policy-based routes. For more information, see Manage policy-based routes.
Before you create a policy-based route, make sure that an IPsec-VPN connection is created. For more information, see CreateVpnConnection .
CreateVpnPbrRouteEntry 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 the DescribeVpnGateway operation to query the status of the VPN gateway.
- If the VPN gateway is in the updating state, the policy-based route is being created.
- If the VPN gateway is in the active state, the policy-based route is created.
You cannot call the CreateVpnPbrRouteEntry operation to create multiple policy-based routes for a VPN gateway at a time.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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.

Operation	Access level	Resource type	Condition key	Associated operation
vpc:CreateVpnPbrRouteEntry	create	VpnGateway acs:vpc:{#regionId}:{#accountId}:vpngateway/{#VpnGatewayId}	none	none

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the VPN gateway. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate a 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 is different for each request.	d7d24a21-f4ba-4454-9173-b3****
VpnGatewayId	string	Yes	The VPN gateway ID.	vpn-bp1a3kqjiiq9legfx****
RouteSource	string	Yes	The source CIDR block of the policy-based route.	192.168.1.0/24
RouteDest	string	Yes	The destination CIDR block of the policy-based route.	10.0.0.0/24
NextHop	string	Yes	The next hop of the policy-based route.	vco-bp15oes1py4i66rmd****
Weight	integer	Yes	The weight of the policy-based route. If you use the same VPN gateway to establish active/standby IPsec-VPN connections, you can configure route weights to specify which connection is active. A value of 100 specifies the active connection, whereas a value of 0 specifies the standby connection. You can configure health checks to automatically check the connectivity of IPsec-VPN connections. If the active connection is down, the standby connection automatically takes over. For more information, see CreateVpnConnection . 100: The IPsec-VPN connection associated with the policy-based route serves as an active connection. 0: The IPsec-VPN connection associated with the policy-based route serves as a standby connection. Note If you specify active/standby IPsec-VPN connections, the active policy-based route and the standby policy-based route must have the same source and destination CIDR blocks.	0
PublishVpc	boolean	Yes	Specifies whether to advertise the policy-based route to a virtual private cloud (VPC) route table. Valid values: true false	true
Description	string	No	The description of the policy-based route. The description must be 1 to 100 characters in length, and cannot start with http:// or https://.	desctest
OverlayMode	string	No	The tunneling protocol. Set the value to Ipsec.	Ipsec
Priority	integer	No	The priority of the policy-based route. Valid values: 1 to 100. Default value: 10. A smaller value indicates a higher priority.	10
