This topic describes how to associate an Anycast elastic IP address (Anycast EIP) with a backend server. After an Anycast EIP is associated with a backend server, users can use the Anycast EIP to communicate with the backend server over the Internet. This improves user experience of Internet access.

Prerequisites

An internal-facing Server Load Balancer (SLB) instance is created. The SLB instance must be deployed in a virtual private cloud (VPC). For more information, see Create an SLB instance.

Procedure

  1. Log on to the Anycast EIP console.
  2. On the Anycast Elastic IP Addresses page, find the Anycast EIP that you want to manage, and click Bind in the Actions column.
  3. In the Bind Anycast EIP to a Resource dialog box, set the following parameters.
    Associate an Anycast EIP with a backend server
    Parameter Description
    Instance Type Select the type of backend server with which you want to associate the Anycast EIP. Default value: SLB instance:
    Note This value specifies an internal-facing SLB instance that is deployed in a VPC. Anycast EIPs can be associated with only internal-facing SLB instances that are deployed in VPCs.
    Resource Group Select the resource group to which the SLB instance belongs.
    Region Select the region where the SLB instance is created.

    You can associate an Anycast EIP with a SLB instance that is deployed in the China (Hong Kong), India (Mumbai), UK (London), Malaysia (Kuala Lumpur), US (Silicon Valley), or Singapore (Singapore) region.

    Select the instance to bind Select the SLB instance with which you want to associate the Anycast EIP.
    Notice When you associate an Anycast EIP with an internal-facing SLB instance that is deployed in a VPC, transient connection errors may occur when network traffic traverses within the VPC. Therefore, we recommend that you perform the operation during off-peak hours or switch the workloads to another instance first.
  4. Click OK.
