Adding EIPs to or Removing EIPs from a Shared Bandwidth

Scenarios

You can add EIPs to a shared bandwidth as required to share the bandwidth and reduce public network bandwidth costs. You can also remove EIPs from a shared bandwidth.

You can add multiple EIPs to a shared bandwidth at the same time.

Constraints

To add an EIP to a shared bandwidth, the EIP must use the pay-per-use billing, be in the same region, and be of the same type as the shared bandwidth.
To add a yearly/monthly EIP to a shared bandwidth, you need to first change its billing mode to pay-per-use.
After an EIP is added to a shared bandwidth:
- The cloud service instance bound to the EIP uses the shared bandwidth.
- The original peak bandwidth of the EIP becomes invalid, and the EIP uses the peak bandwidth of the shared bandwidth.
- The original billing mode of the EIP becomes invalid, and the EIP traffic or bandwidth is no longer billed.
- The EIP reservation price is irrelevant to whether the EIP is added to a shared bandwidth.

Procedure

You can add EIPs to a shared bandwidth on the console or by calling an API.

Go to the shared bandwidth list page.
In the shared bandwidth list, locate the target shared bandwidth that you want to add EIPs to. In the Operation column, choose Add Public IP Address.
On the Add Public IP Address page, select the EIPs or IPv6 addresses to be added.
You can add an EIP to a shared bandwidth even if it is already added to another shared bandwidth. Adding an EIP to a new shared bandwidth automatically removes it from the original one.

After an EIP is added to a shared bandwidth, its dedicated bandwidth becomes invalid and the EIP starts using the shared bandwidth. The EIP's dedicated bandwidth is then deleted and no longer billed.
Click OK.

You can call the API to add EIPs to a shared bandwidth. For details, see Adding an EIP to a Shared Bandwidth.

Procedure

You can remove EIPs from a shared bandwidth on the console or by calling an API.

Go to the shared bandwidth list page.

In the shared bandwidth list, locate the row that contains the bandwidth from which EIPs are to be removed, choose More > Remove Public IP Address in the Operation column.
On the Remove Public IP Address page, select the EIPs or IPv6 addresses to be removed.
Configure the EIP bandwidth after the EIP is removed. You can modify the EIP billing mode and bandwidth size.
Click OK.

An EIP remains unchanged after it is removed from a shared bandwidth. The EIP bandwidth is billed based on its billing mode before the EIP is added to the shared bandwidth.
