This topic describes how to configure a cross-region connection bandwidth. To connect networks in different regions, you must configure a cross-region connection bandwidth after purchasing a bandwidth package.

Background information

The sum of all cross-region connection bandwidth values cannot exceed the bandwidth of the bandwidth package. By default, 1 Kbit/s bandwidth is provided for cross-region connections. This default bandwidth is provided for you to perform connectivity tests. To run normal services, you must buy a bandwidth package and set a proper cross-region connection bandwidth.

Assume that you have bought a bandwidth package of 20 Mbit/s for a Cloud Enterprise Network (CEN) instance and the connected areas are Mainland China and North America. You can set a cross-region connection bandwidth between US (Virginia) and China (Hangzhou), China (Shanghai), China (Shenzhen), or other regions. However, the total bandwidth values set for all cross-region connections cannot exceed 20 Mbit/s.

Procedure

  1. Log on to the CEN console.
  2. On the Instances page, find the target CEN instance and click Manage in the Actions column.
  3. Click the Region Connections tab, and click Set Region Connection.
  4. In the displayed Set Region Connection dialog box, configure the cross-region connection bandwidth and click OK.
    Configuration Description
    Bandwidth Packages Select the bandwidth package attached to the CEN instance.
    Connected Regions Select the regions to be connected.
    Bandwidth Enter the required bandwidth value for the connected regions.
