Which source of routing information is preferred by default?

Static routes have a default preference value (e.g., 5 on Junos) that is higher (less preferred) than direct routes.

RIP routes have a relatively high default preference value (e.g., 100 on Junos), making them less preferred than direct routes.

Directly connected routes are inherently the most preferred source of routing information, possessing the lowest default preference value (administrative distance, typically 0 on Juniper devices). This ensures that a router will always use an interface to which a network is directly attached if it is operational, over any other learned or static route for the same destination.

BGP routes have default preference values (e.g., 170 for both IBGP and EBGP on Junos) that are significantly higher than direct routes, indicating lower preference.
