This topic describes how to synchronize the routes between a Smart Access Gateway (SAG) instance and the corresponding on-premises SAG device.

Procedure

  1. Log on to the Smart Access Gateway console.
  2. In the left-side navigation pane, click Smart Access Gateway, and then click the target instance ID or click Configure Network in the Actions column.
  3. On the SAG instance details page, click Method to Synchronize with On-premises Routes.
  4. Select the method to synchronize the SAG instance routes with the on-premises device routes.
    The following two methods are available:
    • Static Routing: The SAG instance and the on-premises SAG device are interconnected through static routing. After you add the on-premises static routes, they are automatically published to the CEN.
      1. Click Add Static Routing.
      2. In the Add Static Routing dialog box, set the private CIDR block that is used by the on-premises SAG device to access Alibaba Cloud.
        Note By default, up to five static routing CIDR blocks can be configured. However, you can open a ticket to increase the quota to 20.
      3. Click OK.
    • Dynamic Routing: The SAG instance and the on-premises SAG device are interconnected through dynamic routing. After you add the on-premises dynamic routes, the BGP or OSPF protocol is run to automatically learn the on-premises routes.
