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 Resourcesis 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.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| RegionId | string | Yes | The region ID of the BGP group. You can call the DescribeRegions operation to query the most recent region list. | cn-shanghai |
| BgpGroupId | string | Yes | The BGP group ID. | bgpg-wz9f62v4fbg2g**** |
| Name | string | No | The BGP group name. The name must be 2 to 128 characters in length, and can contain digits, periods (.), underscores (_), and hyphens (-). The name must start with a letter but cannot start with | test |
| Description | string | No | The BGP group description. The description must be 2 to 256 characters in length. It must start with a letter and cannot start with | BGP |
| LocalAsn | long | No | The custom autonomous system number (ASN) of the BGP on the Alibaba Cloud side. Valid values:
Note
65025 is reserved by Alibaba Cloud. Alibaba Cloud uses 45104 as the local ASN by default. Custom local ASNs may cause loops in multi-line scenarios. Proceed with caution.
| 45104 |
| PeerAsn | long | No | The ASN of the gateway device in the data center. | 1**** |
| AuthKey | string | No | The authentication key of the BGP group. | !PWZ2**** |
| IsFakeAsn | boolean | No | Specifies whether to use a fake AS number. Valid values:
Note
A router that runs BGP typically belongs to only one AS. If you need to replace an AS with a new one, but you cannot immediately modify BGP configurations due to business requirements, you can specify a fake AS number to establish a connection with the local end. This ensures service continuity in scenarios such as AS migration or AS merging.
| false |
| 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-a456-426655440000 |
| RouteQuota | integer | No | The maximum number of routes supported by a BGP peer. Default value: 110. | 110 |
| ClearAuthKey | boolean | No | Specifies whether to clear the secret key. Valid values:
| false |
