How to Configure Source-Based Routes

  • Last updated on

Source-based routing, often referred to as policy routing, is used when the source IP address of the connection determines, in part or completely, which route is used. Source-based routing can be used to ensure that traffic is sent via a specific connection. For each source-based routing entry, a routing table for that specific IP address/network is created and consulted when traffic from that network comes in.

Step 1. Create a Source-Based Route

  1. Open the Network page (Config Full Config > Box).
  2. In the left menu, click Routing.
  3. Click Lock.
  4. In the Source Based Routing section, add or edit an entry for your route in the Routing Rules table:
    1. Name – Enter a name. E.g., route1
    2. Source Networks – Add the source IP address or network. E.g., 10.0.10.0/24
    3. Routes – Click + to add a route table entry for the source network.
      • Target Network Address – Enter the target network IP address. E.g., 0.0.0.0/0 
      • Route Type – Select unicast, multipath or throw. If throw is selected, the route lookup will end once the first matching route is found.
      • Gateway (only for unicast routes) – Enter the IP address of the remote gateway.
      • Multipath Gateway (only for multicast routes) – Enter the Multipath Gateway and Weight Number (Metric) for each route.
      • Packet Load Balancing (only for multicast routes) – If needed, enable packet load balancing.
      • Route Metric (only for unicast routes) – Enter the route metric for the gateway route.
      • Advertise Route – Select YES if you want to use dynamic routing service. For more information, see Dynamic Routing Protocols (OSPF/RIP/BGP).
  5. Select where the route table is placed, before (premain) or after (postmain) the main routing table.
  6. Click OK.
  7. Click Send Changes and Activate.

Step 2. Activate the New Network Configuration

After you have configured the network route, you must execute your new network configurations.

  1. Go to the Control > Box page.
  2. In the left navigation pane, expand Network and then click Activate new network configuration.
  3. Select Failsafe. The Failsafe Activation Succeeded message is displayed after your new network configurations have been successfully activated.
  4. Click OK.
