If a routing policy is specified in this command, the preference (if any) set by the routing policy applies to
those matched routes. Other routes use the preference set by the preference command.
When a router runs multiple routing protocols at the same time, the system will configure a preference
to each routing protocol. If several protocols find routes to the same destination, the route of the routing
protocol with the highest preference is selected.
