CreateVpd-阿里云帮助中心

Create a private Lingjun CIDR block. This CIDR block has an independent network environment.

Operation description

When you call this operation to create a CIDR block for Lingjun, take note of the following:

A Lingjun network segment can specify an additional network segment in addition to a main network segment.
After the Lingjun network segment is created, the network segment cannot be modified.
Make sure that you have a sufficient quota of Lingjun CIDR blocks.
This interface is an asynchronous interface. After calling this interface, the system will return the ID of a Lingjun network segment. At this time, the Lingjun network segment may not be created yet, and the system background creation task is still in progress. You can call the ListVpds or GetVpd operation to query the status of the CIDR block of Lingjun.
- If the status of the Lingjun CIDR block is Executed, the CIDR block is being created.
- If the status of the Lingjun CIDR block is Available, the creation is successful.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the disk.	cn-wulanchabu
VpdName	string	Yes	Lingjun CIDR block instance name	vpd-1
Cidr	string	Yes	The CIDR block of the VPD. We recommend that you use an RFC private endpoint as the Lingjun CIDR block, such as 10.0.0.0/8,172.16.0.0/12,192.168.0.0/16. In scenarios where the Doringjun CIDR block is connected to each other or where the Lingjun CIDR block is connected to a VPC, make sure that the addresses do not conflict with each other. You can also use a custom CIDR block other than 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, or 169.254.0.0/16 and their subnets as the primary IPv4 CIDR block of the VPD.	10.0.0.0/8
Subnets	array<object>	No	Lingjun subnet information list
	object	No	Lingjun subnet information
SubnetName	string	No	Lingjun subnet instance name	subnet-1
RegionId	string	No	The region in which the instance resides.	cn-wulanchabu
ZoneId	string	No	The zone ID of the disk.	cn-wulanchabu-b
Cidr	string	No	The CIDR block of the Subnet. The network segment of the subnet must be a proper subset of the network segment of Lingjun to which it belongs, and the mask must be between 16 bits and 29 bits, which can provide 8 to 65536 addresses. For example, the CIDR block of the Lingjun CIDR block is 192.168.0.0/16, and the CIDR blocks of the subnets under the Lingjun CIDR block are 192.168.0.0/17 to 192.168.0.0/29. The first and last three IP addresses of each subnet segment are reserved by the system. For example, the CIDR blocks of the subnet are 192.168.1.0/24,192.168.1.0, 192.168.1.253, 192.168.1.254, and 192.168.1.255.	10.1.0.0/16
Type	string	No	Lingjun Subnet Usage Type; optional; optional. Valid values: Generic type is not specified. OOB :OOB type LB: LB type	OOB
ResourceGroupId	string	No	The resource group ID. For more information about resource groups, see Resource groups.	rg-aek2l4sq6l7unhi
Tag	array<object>	No	A tag.
	object	No	The tag information. You can specify up to 20 tags.
Key	string	No	The tag key of the VPN attachment. You cannot specify an empty string as a tag key. It can be up to 64 characters in length and cannot start with aliyun or acs:. It cannot contain http:// or https://. You can specify at most 20 tag keys in each call.	vpd-wulanchabu
Value	string	No	The tag value of the VPN connection. The tag value can be empty or a string of up to 128 characters. It cannot start with aliyun or acs:, and cannot contain http:// or https://. Each tag key corresponds to a tag value. You can enter a maximum of 20 tag values at a time.	wulanchabu-a
