Settings

Before you turn on dynamic routing protocols (BGP, OSPFv2, OSPFv3, RIP, or RIPng), configure the global routing preferences and the Equal-Cost Multi-Path (ECMP) learning behavior on the firewall. The following procedure also shows how to turn on BGP.

To enable Dynamic Routing Settings

1. Navigate to NETWORK | System > Dynamic Routing | Settings.

   

2. (Optional) Turn on Prioritize routes by metric within route classes.
3. Select Advanced Routing Mode. A confirmation message displays.

4. From the BGP drop-down menu, select Enabled.

5. In the Apply the following metric to default routes received from Advanced Routing protocols field, enter a metric value. The default value is 110.

   SonicOS applies the metric to default routes that the firewall learns through advanced routing protocols.

6. To install several equal-cost routes to the same destination, turn on Allow learning ECMP routes from advanced routing protocols. When the warning message displays, click OK.

   This change takes effect after the firewall restarts. For information about BGP ECMP, refer to Border Gateway Protocol.

7. To generate detailed diagnostic and debugging information for troubleshooting, turn on Enable granular debug in routing protocols.

   Turn on this option only when you troubleshoot routing issues. Detailed debugging might increase logging activity and resource use.
