This topic describes how to use Cloud Enterprise Network (CEN) to connect the networks that belong to the same region and the same account.

Prerequisites

  • VPCs or Virtual Border Routers (VBRs) are created.

  • The VPCs and VBRs to be connected do not use Express Connect.

Step 1 Create a CEN instance

  1. Log on to the CEN console.
  2. On the Instances page, click Create CEN instance.
  3. Configure the CEN instance.
    • Name: Enter a name for the CEN instance to be created. The name must be 2 to 128 characters in length and can contain letters, numbers, hyphens (-), and underscores (_). The name must start with a letter or a Chinese character. In this example, enter SameAccountsSameRegion.
    • Description: Enter a description for the CEN instance to be created. The description must be 2 to 256 characters in length and cannot start with http:// or https://.
    • Attach Network:

      • Network Type: Select the type of the network to attach. You can attach a VPC, a VBR, or a Cloud Connect Network (CCN). In this example, select VPC
      • Region: Select the region of the network. In this example, select China (Qingdao).
      • Networks: Select the instance to attach. In this example, select a VPC.

Step 2 Attach networks

  1. On the Instances page, find the created CEN instance, and click Manage in the Actions column.


  2. On the Networks tab, click Attach Network and configure the network as follows:
    • Account: Click the Different Account tab.
    • Network Type: Select the type of the network to attach. You can attach a VPC, a VBR, or a CCN. In this example, select VPC.
    • Region: Select the region of the network. In this example, select China (Beijing).
    • Networks: Select the instance to attach. In this example, select a VPC.


Step 3 Test the connectivity

Log on to any ECS instance in an attached network and ping the private IP address of another ECS instance in another attached network to test the connectivity.

Note Make sure that corresponding authorization rules are configured in the security groups of the ECS instances.
