When you do not need Smart Access Gateway devices added to a CCN instance to communicate with networks (VPCs or VBRs) in the CEN instance, you can detach the CCN instance from the CEN instance.

Procedure

  1. Log on to the Smart Access Gateway console.
  2. In the left-side navigation pane, click CCN.
  3. Select the area where the target CCN instance belongs, and click Unbind CEN Instance in the Actions column.
  4. In the displayed dialog box, click OK. After you detach the CEN instance, the CCN instance cannot communicate with resources (VPCs and VBRs) in the CEN instance.
