Administrative distance – Which route is the best?

Administrative distance is the measure used by Cisco routers to help them decide how to select the best path when there’s more that one route to the same destination from different routing protocols. We can say that in this manner administrative distance shows the real reliability of a routing protocol in one system. It shows which routes are more important based on the routing protocol from which they derived. Each routing protocol is prioritized in order of most to least reliable using an administrative distance value. Don’t get confused, a lower numerical value is preferred. For example, an EIGRP with an administrative distance of 90 will be chosen over a RIP route with an administrative distance of 120 and over OSPF route with an administrative distance of 110 to.

Here is a table with all default administrative distances used by Cisco routers:

Difference between Routed and Routing Protocols

Routed Protocols vs. Routing Protocols
RoutingIn this article we will cover the difference between Routed Protocols and Routing Protocols. This is one of the thing that can be asked of you if you are attending a job interview or if you are going to CCNA exam so, you must know the difference between a “routed” protocol and a “routing protocol” as one of the key concepts in the Routing world and networking world.
