To create a dedicated connection over an Express Connect circuit, you must contact a network carrier to connect your data center to an Alibaba Cloud access point with a dedicated Express Connect circuit. You must confirm the access point and purchase an Express Connect circuit in the console.

Background information

To connect your data center to an Alibaba Cloud access point with a dedicated Express Connect circuit, perform the following steps:

  1. Prepare the connection information.

    Before you apply for a physical connection, you must obtain the detailed location of the access point and available resources, ask the service provider to perform a site survey, and get a price quote. For more information, see Preparations.

  2. Apply for and enable a physical connection interface.

    This process involves operations of the customer, service provider, and Alibaba Cloud. The console displays the required operations and connection states at all stages.

  3. Create a Virtual Border Router (VBR) to connect the on-premises data center to an Alibaba Cloud VPC.

For more information, see Process of creating a dedicated physical connection.

Step 1: Preparations

Before you apply for an Express Connect circuit in the console, you must confirm the access point. In addition, make sure that your network carrier has completed the pre-installation site survey. For more information, see Preparations.

Step 2: Apply for an Express Connect circuit in the console

After you confirm the access method and the network carrier completes the pre-installation site survey, you can apply for an Express Connect circuit in the console. You can view the status of the Express Connect circuit that you applied for in the console. The following figure describes the procedure to enable an Express Connect circuit.

Note The time to review the Letter of Authorization (LOA) and install the Express Connect circuit is subject to public holidays and local laws.

To apply for an Express Connect circuit, perform the following operations:

  1. Log on to the Express Connect console.
  2. In the left-side navigation pane, click Exclusive Physical Connection.
  3. Click Apply for New Interface.
  4. Set the parameters for the Express Connect circuit and complete the payment for the initial installation.
    Parameter Description
    Region and Zone Select the region where you want to create a dedicated connection over an Express Connect circuit.

    We recommend that you select the region where the virtual private cloud (VPC) that you want to access is deployed. If the VPC is deployed in a different region, you must use the Cloud Enterprise Network (CEN) service to create a cross-region connection. In this case, you will be charged for the cross-region connection.

    SP Select the network carrier from which you want to lease an Express Connect circuit. The access points to which you can connect an Express Connect circuit vary based on the network carrier.
    Note
    • If you lease an Express Connect circuit from China Unicom, China Telecom, or China Mobile, you cannot use cables from other network carriers to establish the Express Connect circuit.
    • China Unicom, China Telecom, and China Mobile do not support connections through bare fiber cables provided by third-party network carriers.
    Access Point

    Select the access point that is nearest to your data center.

    Access points are Alibaba Cloud data centers located in different regions. One or more access points are deployed in each region. The access points allow you to connect to Alibaba Cloud from different geographic locations and support different connection types.

    Understand Billing Rules Make sure that you understand the billing rules of Express Connect circuits. For more information, see Billing.

    Read the billing rules and click Yes.

    Port Specification You are charged a resource usage fee based on the port specification. We recommend that you select a port specification based on your business requirements.
    • If the bandwidth limit of the Express Connect circuit is lower than 1 Gbit/s, select 1 G and below.
    • If the bandwidth limit of the Express Connect circuit is higher than 1 Gbit/s, select 10 G.
    • To upgrade the bandwidth limit of an Express Connect circuit from 500 Mbit/s to 2 Gbit/s, contact your network carrier. Then, contact your product manager from Alibaba Cloud to change the optical transceiver module.
    Note To use 40 Gbit/s and 100 Gbit/s ports, you must be included in a whitelist.
    Port Type

    You can select a copper port or an optical port.

    Redundant Connection ID Select an Express Connect circuit that is already enabled. This allows you to configure equal-cost multi-path routing (ECMP). When one of the two Express Connect circuits is down, network traffic is transmitted through the other Express Connect circuit.
    • If the Express Connect circuits are connected to different access points, you do not need to specify the secondary Express Connect circuit.
    • If the Express Connect circuits are connected to the same access point, you must specify one of them as the secondary Express Connect circuit. The primary and secondary Express Connect circuits are allocated to different devices.
