Use a BGP (Multi-ISP) Pro EIP to optimize access from the Chinese mainland to global services - Elastic IP Address

Services deployed in regions outside the Chinese mainland, such as China (Hong Kong), may experience high network latency when serving users within the mainland due to inefficient public internet routing. You can associate a BGP (Multi-ISP) Pro EIP with your service to route traffic over dedicated carrier lines, reducing access latency for users in the Chinese mainland.

Availability

The supported regions vary based on the billing method:

pay-as-you-go: China (Hong Kong), Indonesia (Jakarta), Japan (Tokyo), Malaysia (Kuala Lumpur), Philippines (Manila), Singapore, and Thailand (Bangkok).
subscription: China (Hong Kong).

Create and associate a BGP (Multi-ISP) Pro EIP

Create an EIP:
1. Go to the EIP console and click Create EIP.
2. Configure the EIP parameters and complete the purchase. For information about other parameters, see EIP Configurations.
  - Billing Method: Select a billing method available in the deployment region.
  - Region: Select the region where your resources are deployed.
  - Line Type: Select BGP (Multi-ISP) Pro.
  - IP Address Pool: If you have an IP address pool, select it to allocate the EIP.
Associate the EIP with a cloud resource:
1. Go to the EIP page. In the top navigation bar, select the region where the EIP is located.
2. Find the target EIP, click Associate with Resource in the Actions column, and then select the instance type and the specific instance.

Verify network performance

Public network quality depends on carrier performance. We recommend that you test the performance for your specific service.

This example shows how to test the access latency from an ECS instance in the China (Hangzhou) region to two ECS instances in the Philippines (Manila) region. One instance is associated with a BGP (Multi-ISP) EIP and the other with a BGP (Multi-ISP) Pro EIP.

Configure the Nginx service on both ECS instances in the Philippines (Manila) region.
```
sudo yum install nginx -y
sudo systemctl start nginx
```

Test the access latency from the ECS instance in the China (Hangzhou) region.

Make sure that the security group rules of the ECS instances in the Philippines (Manila) region allow access from the public IP address of the ECS instance in the China (Hangzhou) region.

BGP (Multi-ISP) Pro EIPs and BGP (Multi-ISP) EIPs are priced differently. For more information, see pay-as-you-go and subscription.

FAQ

EIP to Pro EIP conversion

No. The line type for an EIP can only be selected during creation and cannot be changed afterward.
