The Administrative Distance (AD) is a value used by routers to determine the preferred route when multiple routing protocols provide different paths to the same destination.
Here are the default Administrative Distance values for commonly used routing protocols :
These values represent the default AD values assigned by the routing protocols. It's important to note that these values can be manually adjusted in router configurations if desired, allowing network administrators to influence the preferred routing paths. Lower AD values indicate a higher preference for a particular route.
