Modifies the configuration of a Border Gateway Protocol (BGP) group.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes ModifyBgpGroupAttribute

The operation that you want to perform. Set the value to ModifyBgpGroupAttribute.

RegionId String Yes cn-shanghai

The ID of the region to which the BGP group belongs.

You can call the DescribeRegions operation to query the most recent region list.

BgpGroupId String Yes bgpg-wz9f62v4fbg2g****

The ID of the BGP group.

Name String No test

The name of the BGP group.

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 and cannot start with http:// or https://.

Description String No BGP

The description of the BGP group.

The description must be 2 to 256 characters in length. The description must start with a letter but cannot start with http:// or https://.

LocalAsn Long No 45104

The autonomous system (AS) number of the device on the Alibaba Cloud side.

PeerAsn Long No 1****

The AS number of the on-premises device.

AuthKey String No !PWZ2****

The authentication key of the BGP group.

IsFakeAsn Boolean No true

Specifies whether to use a fake AS number. Valid values:

  • false (default): no
  • true: yes
Note A running BGP router typically belongs to only one AS. If you want to replace the current AS with a new one (for example, the current AS needs to be migrated or merged with another one) and you cannot modify BGP configurations, you can specify a fake AS number to establish connections to the on-premises device. This ensures that your services are not interrupted.
ClientToken String No 123e4567-e89b-12d3-a456-426655440000

The client token that is used to ensure the idempotence of the request.

You can use the client to generate the value, but you must make sure that it is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length.

Note If you do not set this parameter, the system automatically uses RequestId as ClientToken. RequestId may be different for each API request.

Response parameters

Parameter Type Example Description
RequestId String 8C3C6D7C-A1CE-4FD8-BC57-DC493A55F76F
