This topic describes how to use Cloud Enterprise Network (CEN) to connect network instances that are created by the same account and in the same region.
Step 1: Create a CEN instance
- Log on to the CEN console.
- On the Instances page, click Create CEN instance.
- Set the following parameters to create a CEN instance:
- Name: Enter a name for the CEN instance. The name must be 2 to 128 characters in length and can contain digits, underscores (_), and hyphens (-). The name must start with a letter or Chinese character. In this example, SameAccountSameRegion is entered.
- Description: Enter a description for the CEN instance. You can leave this parameter empty. The
description must start with a Chinese character or English letter, and cannot start
https://. The description must be 2 to 256 characters in length, and can contain Chinese characters, English letters, digits, hyphens (-), and periods (.), underscores (_). It can also contain characters or letters from other languages.
- Attach Network:
- Network Type: Specify the type of network instance to be attached to the CEN instance. You can select virtual private cloud (VPC), virtual border router (VBR), or Cloud Connect Network (CCN). In this example, VPC is selected.
- Region: Select the region where the network instance to be attached is created. China (Qingdao) is selected in this example.
- Networks: Select the network instance that you want to attach to the CEN instance. In this example, a VPC is selected.
Step 2: Attach network instances to the CEN instance
- On the Instances page of the CEN console, find the CEN instance that you created and click Manage in the Actions column.
- On the Networks tab, click Attach Network and set the following parameters to attach network instances:
- Account: Select Your Account.
- Network Type: Select the type of network instance to be attached to the CEN instance. You can select VPC, VBR, or CCN. In this example, VPC is selected.
Step 3: Test the connectivity
To test the connectivity, log on to an Elastic Compute Service (ECS) instance in an
attached network instance. Then, run the
ping command to ping the private IP address of another ECS instance that is deployed in
another attached network instance.
