After a virtual border router (VBR), a Cloud Connect Network (CCN) instance, and a virtual private cloud (VPC) are attached to a Cloud Enterprise Network (CEN) instance, the VBR and CCN instance can access the cloud services deployed in the VPC. This topic describes how to access cloud services deployed in a VPC through CEN.

Prerequisites

  • The VPC where the cloud services that you want to access are deployed is attached to a CEN instance.
  • The VBR or CCN instance to which your on-premises network is connected is attached to the CEN instance to which the VPC belongs. For more information, see Attach networks.

Background information

Cloud services are Alibaba Cloud services (such as OSS, SLS, and DTS) that use the 100.64.0.0/10 CIDR block to provide services. After a VPC, a VBR, and a CCN instance are attached to a CEN instance, your on-premises network can access the cloud services deployed in the VPC. Access cloud services through CEN 2.1

Procedure

  1. Log on to the CEN console.
  2. On the Instances page, click the ID of the CEN instance that you want to manage.
  3. Click the AnyTunnel tab. Then click SetAnyTunnelService.

  4. In the SetAnyTunnelService panel, set the following parameters:
    • Service IP address: Enter an IP address or CIDR block used by the cloud service that you want to access. This IP address or CIDR block must belong to the CIDR block 100.64.0.0/10. Example: 100.118.28.52/32.
    • Service Region: Select the region to which the cloud service that you want to access belongs.
      Note Make sure that at least one VPC in the selected region is attached to the CEN instance.
    • Host VPC: Select the VPC that is attached to the CEN instance.

      After you set the preceding parameters, the VBR or CCN instance can access the cloud service through the VPC.

    • Access Region: Select the region to which the VBR or CCN instance that needs to access the cloud service belongs.
      Note
      • Make sure that the VBR or CCN instance is attached to the CEN instance.
      • A VBR can access only cloud services that are deployed in the region to which the VBR belongs.
    • Description: Optional. Enter a description for the cloud service.

      The description must be 2 to 256 characters in length, and can contain digits, hyphens (-), periods (.), and underscores (_). It must start with a letter or a Chinese character and cannot start with http:// or https://.

  5. Click OK.
    Note Typically, a cloud service uses multiple IP addresses. Repeat the preceding steps to add routes for all IP addresses of the cloud service that you want to access.
