Assigning a Global EIP

Scenarios

This section describes how to assign a global EIP. Global EIPs can be bound to cloud instances (such as ECSs or load balancers) from any region so that these instances can access the Internet. You can specify the access point, type, and global EIP pool based on your service requirements on Internet access.

If you want to assign a global EIP, submit a service ticket to apply for permissions.

Procedure

  1. Go to the Assign Global EIP page.
  2. Configure the parameters based on Table 1.
    Table 1 Parameter descriptions

    Parameter

    Description

    Example Value

    Region

    Mandatory

    For details about regions, see Selecting a Region.

    CN East-Shanghai1

    City

    Mandatory

    A global internet bandwidth can only be shared by global EIPs from its same city.

    Shanghai

    Type

    Select Global EIP or Global EIP range.

    Global EIP

    Version

    Select IPv4 or IPv6.

    IPv4

    Global EIP Type

    Mandatory

    • You can select:
      • Static BGP
      • Dynamic BGP

      Reverse resolution is not supported for static single-line IP addresses (non-cloud vendor IP addresses).

    • After you select a global EIP pool, the system will allocate a global EIP to you from the pool. Select a resource pool close to your business to minimize the latency.

    -

    Mask Length

    This parameter is available only when Type is set to Global EIP range. You can call the following API obtain all available mask lengths:

    GET /v3/{domain_id}/global-eip-segments/support-masks

    24

    Global Internet Bandwidth

    Mandatory

    • Assign now: Select this option if you want to purchase a new global internet bandwidth.
    • Use existing: Select this option if you want to add the global EIP to an existing global internet bandwidth for internet access.

    -

    Billing Mode

    You can select:

    • Yearly/Monthly
    • Pay-per-use

    Pay-per-use

    Bandwidth Type

    You can select:

    • Standard
    • IPv6 Static Bandwidth

    Standard

    Billed By

    This parameter is available only when Billing Mode is set to Pay-per-use. You can select:

    • 95th percentile bandwidth (standard)
    • 95th percentile bandwidth (bidirectional)

    95th percentile bandwidth (standard)

    Guaranteed Bandwidth

    This parameter is available only when Billing Mode is set to Pay-per-use. The system automatically generates the guaranteed bandwidth percentage based on what you select for Billed By.

    0%

    Bandwidth (Mbit/s)

    The bandwidth size in Mbit/s.

    300

    Global EIP Name

    Optional

    Enter the name of the global EIP. The name:
    • Must contain 0 to 64 characters.
    • Can contain letters, digits, underscores (_), hyphens (-), and periods (.).

    g-eip01

    Enterprise Project

    The enterprise project that the global EIP belongs to.

    An enterprise project facilitates project-level management and grouping of cloud resources and users. The default project is default.

    For details about creating and managing enterprise projects, see the Enterprise Management User Guide.

    default

    Advanced Settings

    Click the drop-down arrow to configure parameters, including the bandwidth name and tag.

    Retain the default settings.

    Bandwidth Name

    Optional

    Enter the name of the bandwidth. The name:
    • Must contain 0 to 64 characters.
    • Can contain letters, digits, underscores (_), hyphens (-), and periods (.).

    ibw-test

    Tag

    Global EIP tag, which consists of a key and value pair.

    The tag key and value must meet the requirements listed in Table 2.
    • Key: geip_1
    • Value: 184.100.101.102

    Monitoring

    This function is free. With Cloud Eye, you can monitor:

    • Network traffic at one-minute intervals.
    • Bandwidth fluctuations and inbound and outbound bandwidth rates.

    -

    Quantity

    This parameter is available only when Type is set to Global EIP. Number of global EIPs to be assigned.

    3

    Required Duration

    The duration for which the yearly/monthly global EIP will be used.

    1 month

    Upon Expiration

    This parameter must be specified if the Billing Mode is set to Yearly/Monthly. The value can be one of the following:

    • Change to pay-per-use
    • Auto-renew
    • Enter grace period

    Change to pay-per-use

    • Cannot be left blank.
    • Must be unique for a global EIP.
    • Can contain a maximum of 128 characters.
