Example: Configuring Source-Based Routes (NSM Procedure)

In this example, you want to forward traffic from the 10.1.1.0/24 subnetwork to ISP 1, and forward traffic from the 10.1.2.0/24 subnetwork to ISP 2. You must configure two entries in the default trust-vr routing table and enable source-based routing. The subnetwork 10.1.1.0/24, with ethernet1 as the forwarding interface, uses the ISP 1 router (1.1.1.1) as the next hop; subnetwork 10.1.2.0/24, with ethernet2 as the forwarding interface, uses the ISP 2 router (2.2.2.2) as the next hop.

  1. In the NSM navigation tree, select Device Manager > Devices. Double-click the device object to open the device configuration.
  2. In the device navigation tree, select Network > Virtual Routers. Double-click the trust-vr virtual router. The General Properties screen appears.
  3. In the virtual router navigation tree, select Routing Table.
  4. Select Enable Source-Based Routing.
  5. Add the first routing entry. In the Source-Based Routing Table area, click the Add icon. The New Source Routing Table dialog box appears.
  6. Configure the following options:
    • For IP Address, enter 10.1.1.0.
    • For Network Mask, enter 24.
    • For Interface, select ethernet1.
    • For Gateway, enter the IP address 1.1.1.1.
    • Click OK to save the new routing entry.
  7. Add the second routing entry. In the Source-Based Routing Table area, click the Add icon. The New Source Routing Table dialog box appears.
  8. Configure the following options:
    • For IP Address, enter 10.1.2.0.
    • For Network Mask, enter 24.
    • For Interface, select ethernet2.
    • For Gateway, enter the IP address 2.2.2.2.
    • Click OK to save the new routing entry.
  9. Click OK to save your changes to the device.
