Binding and Unbinding an EIP

Scenarios

You can bind an EIP to a GaussDB instance for public access and can unbind the EIP from an instance as required.

To ensure that the database can be accessed, the security group used by the database must allow access to the database port. For example, if the database port is 1611, ensure that the security group allows access to the port 1611.

Precautions

• If a DB instance has already been bound with an EIP, you must unbind the EIP from the instance first before binding a new EIP to it.
• An EIP can be bound to only one node IP address of a DB instance.

Binding an EIP
