Creating a Global DC Gateway

Scenario

A global DC gateway can be attached to enterprise routers in the same region for network communication. This can reduce the network latency, simplify network topology, and improve network O&M efficiency.

This section describes how to create a global DC gateway and associate an enterprise router with it.

Procedure

Preparations

Before creating resources such as connections, sign up for a HUAWEI ID, enable cloud services, complete real-name authentication, top up your account, confirm the Direct Connect locations, and complete the site survey.

• Signing Up and Completing Real-Name Authentication

  To access the Direct Connect console, you need an account. If you do not have an account, sign up for one.

  For details, see and Completing Real-Name Authentication.

  If you have enabled Huawei Cloud services and completed real-name authentication, skip this step.

• Selecting a Direct Connect Location
  When selecting a location, you need to consider the distance to your on-premises data center, which carrier you want to choose, and which type of port will be used.

  • Distance to your on-premises data center

    Select a location nearest to your on-premises data center to reduce network latency. The telecom carriers and bandwidth capabilities vary at different locations.

  • Carrier

    Select a carrier that can lease a line to you based on your requirements.

  • Port type

    Decide what type of port you want to use, an optical port or electrical port.

    • Optical port: The carrier directly provides a fiber optic transmission path for the end user. The port speed is effectively infinite, only limited by the auto-negotiation rate of the optical modules at both ends, for example, 1GE, 10GE, 40GE, and 100GE.
    • Electrical port: Generally, RJ45 ports are used. The carrier uses an optical transceiver to convert electrical signals to optical signals required on the transmission network. The industry standard is to use this type of port when the bandwidth is less than 100 Mbit/s.
      

      • Currently, 1GE and 10GE single-mode optical ports can transmit data up to 10 km. If you need an optical port to transmit data for more than 10 km, or you need a 40GE or 100GE port, you need to purchase the optical modules by yourself.
      • Ensure that the leased line provider can provide the optical fibers to connect to Direct Connect devices.
      • No O/E conversion device is allowed on Huawei Cloud. Ensure that the leased line provider uses the correct line type to connect to Direct Connect devices.

  To obtain detailed address of a Direct Connect location, contact the Direct Connect manager or submit a service ticket.

• Requesting a Site Survey: After you select a location, contact the carrier for a site survey.
  1. Consult the carrier about how to access the cloud.

     You can contact the Direct Connect manager or submit a service ticket to obtain the detailed address of the equipment room.

  2. Submit an application to Huawei Cloud for conducting a site survey in the equipment room.

     The application must include the name, ID card number, and contact information of the personnel who will go to the equipment room for the site survey.

     

     Pay attention to the following when you request a site survey:

     If the site survey can be completed at the meet-me room of the carrier, you do not need to submit an application.

  3. After the application is approved, Huawei Cloud will assist the carrier in entering the equipment room for completing the site survey within two working days.
  4. Ask the carrier to carry out the site survey and confirm the expenses, including those for:
     • The port (paid to Huawei Cloud) and one-time setup (free for now)
     • The leased line (paid to the carrier)
     • In-building cabling

Step 2: Create a Global DC Gateway

1. Go to the Global DC Gateways page.
2. In the upper left corner of the page, click and select a region and project.
3. In the upper right corner, click Create Global DC Gateway.
4. Configure the parameters based on Table 1.

   Table 1 Parameters for creating a global DC gateway

   Parameter	Example Value	Description

   Enterprise Project	default	Specifies the enterprise project by which global DC gateways are centrally managed. Select an existing enterprise project.
   BGP ASN	64512	Specifies the autonomous system number used on the cloud for a BGP session. You can use the default ASN, or specify an ASN in the range of 64512–65534 or 1–4294967295.
   Tag	example_key1 example_value1	Adds tags to help you identify your global DC gateway. You can change them after the global DC gateway is created.
   Description	-	Provides supplementary information about the global DC gateway. It can contain 0 to 128 characters.

5. Click OK.

   The page for creating a virtual interface is displayed.

   You can continue to create a virtual interface or click Later in the lower part of the page to suspend subsequent operations.

Step 3: Create a Virtual Interface

1. If you select Later for Step 2: Create a Global DC Gateway, locate the global DC gateway and click Create Virtual Interface in the Operation column.

   You can also click Create one in the Virtual Interfaces column.

2. Configure the parameters based on Table 2.

   Table 2 Parameters for creating a virtual interface

   Parameter	Example Value	Description
   Region	EU-Dublin	Specifies the region where the connection resides. You can also change the region in the upper left corner of the console.
   Name	vif-123	Specifies the virtual interface name. The name can contain 1 to 64 characters.
   Virtual Interface Priority	-	Specifies whether the virtual interface will be used prior to other virtual interfaces. There are two options: Preferred and Standard. If multiple virtual interfaces are associated with one Direct Connect device, the load is balanced among virtual interfaces with the same priority, while virtual interfaces with different priorities are working in active/standby pairs.
   Connection	-	Specifies the connection you can use to connect your on-premises network to Huawei Cloud.
   Gateway	Global DC Gateway	Specifies the gateway that the virtual interface connects to. The default option is Global DC Gateway.
   Global DC Gateway	-	Specifies the global DC gateway that will be used.
   VLAN	30	Specifies the ID of the VLAN for the virtual interface. You need to configure the VLAN if you create a standard connection. The VLAN for a hosted connection will be allocated by the carrier or partner. You do not need to configure the VLAN.
   Bandwidth (Mbit/s)	50	Specifies the bandwidth that can be used by the virtual interface. The bandwidth cannot exceed that of the connection or LAG.
   Enterprise Project	default	Specifies the enterprise project by which virtual interfaces are centrally managed. Select an existing enterprise project.

   BGP MD5 Authentication Key	12345678	Specifies the password used to authenticate the BGP peer using MD5. This parameter can be set when BGP routing is selected, and the parameter values on both gateways must be the same. The key contains 8 to 255 characters and must contain at least two types of the following characters: Uppercase letters Lowercase letters Digits Special characters ~!,.:;-_"(){}[]/@#$%^&*+\|=
   Description	-	Provides supplementary information about the virtual interface.
