Admin Distance Template
This table shows values associated with various types of Admin Distance. Admin Distance (AD) is the route preference value assigned to dynamic routes, static routes, and directly connected routes. When the appliance’s Routes table has multiple routes to the same destination, the appliance uses the route with the lowest administrative distance.
