How do you enable dynamic OSF routing on a SonicWall firewall?

To enable dynamic OSF (Optimized Static Forwarding) routing on a SonicWall firewall, it's necessary to change the routing mode to Advanced Routing. Advanced Routing allows for greater flexibility and configuration options to support dynamic routing protocols, which can optimize network performance and adapt to changes in the network environment.

Dynamic routing protocols enable the firewall to automatically adjust routes based on the current network state, making it vital for environments that require high availability and performance. By switching to Advanced Routing, the SonicWall firewall can leverage these capabilities effectively, including the support for dynamic routing protocols that allow it to communicate with other routers and make real-time decisions about the best path for traffic.

The other approaches do not provide the necessary functionality to enable dynamic OSF routing. Basic Routing is limited to static routing only, which does not adapt to network changes. Enabling OSF routing through the Security tab would not pertain to routing modes specifically and disabling all existing routing rules would not facilitate dynamic routing but rather disrupt existing configurations.
