This topic describes how to configure routing synchronization between a Smart Access Gateway (SAG) device and a local terminal in the SAG console.

Procedure

  1. Log on to the Smart Access Gateway console.
  2. Choose one of the following methods to open the Network Configuration tab.
    • Click the ID of the target SAG instance. On the instance details page that appears, click Network Configuration.
    • Find the target SAG instance. In the Actions column, click Network Configuration.
  3. Click Method to Synchronize with On-premises Routes.
  4. Select a synchronization method
    You can select the static routing or dynamic routing method.
    • Static Routing: The SAG device is connected to the on-premises network through static routing. You must enter the private CIDR block that the on-premises network uses to access resources deployed on Alibaba Cloud. After you enter the CIDR block, it is automatically advertised to Cloud Enterprise Network (CEN).
      1. Click Add Static Route.
      2. On the Add Static Route page, configure the private CIDR block that the SAG device uses to access resources deployed on Alibaba Cloud.
        The subnet mask of the CIDR block must be 8 to 32 bits in length, which depends on the private CIDR block that the private network falls into. For example, if the IP address of a local terminal is 192.168.0.100 and the subnet mask is 255.255.0.0, the CIDR block is 192.168.0.0/16.
        Note
        • If the LAN port of an SAG-100WM device uses dynamic routing, the first IP address of the first added CIDR block is the address of the local web console. For example, if the first added CIDR block is 172.16.0.0/16, the address of the local web console is 172.16.0.1.
        • By default, you can configure up to five CIDR blocks for static routing. You can submit a ticket to increase the quota to a maximum of fifty.
      3. Click OK.
    • Dynamic Routing: The SAG device is connected to the local terminal through a dynamic routing protocol: Border Gateway Protocol, or Open Shortest Path First. Both protocols automatically learn the CIDR blocks of the on-premises network.
