Binding a Network Interface to an EIP
Scenarios
You can bind an EIP to a network interface to achieve more flexible and scalable networks.
Each network interface has a private IP address. After the network interface is bound to an EIP, the network interface has both a private IP address and a public IP address. The binding between a network interface and an EIP will not change even after the network interface is detached from an instance. After a network interface is migrated from one instance to another, its private IP address and EIP will be migrated together at the same time.
An instance can have multiple network interfaces attached. If each network interface has an EIP bound, the instance will have multiple EIPs and can provide flexible access services.
