What is the administrative distance of directly connected networks?

Explanation:
Administrative distance is the trust level assigned to a route source, and the router uses the lowest value to choose between multiple routes to the same destination. Routes from directly connected networks come from the router’s own interfaces, so they are considered the most trustworthy and are assigned an administrative distance of 0. That makes them the first choice in the routing table, ensuring destinations reachable on a directly connected link are known and used immediately. For contrast, other sources have higher distances—static routes are typically 1, OSPF is 110, and RIP is 120—so they won’t be preferred over the directly connected route when both exist. Note that 255 is not a typical administrative distance value.
