You can bind EIP to a private Server Load Balancer instance of the VPC network, so that the private Server Load Balancer instance can forward requests from the Internet.
Log on to the VPC console.
Select the target region to view all EIP instances under the region.
If there is no available EIP instance, click Create EIP.
Note: Make sure the EIP instance and the private Server Load Balancer instance to bind are in the same region. For more information, see Apply for an EIP address.
Click Bind in the Actions column of the target EIP.
In the displayed dialog box, follow these steps:
Instance Type: Select SLB Instance.
SLB Instance: Select the SLB instance to bind.
