What Is Administrative Distance?
Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols.

each protocol has its own set AD , like OSPF 110 ,EIGRP has external 170 and internal 90 , EBGP 20 IBGP 200 etc

Feasible distance is specific to the EIGRP protocol itself and how its paths are calculated
Feasible distance is the best metric along a path to a destination network, including the metric to the neighbor advertising that path. Reported distance is the total metric along a path to a destination network as advertised by an upstream neighbor.

Do you really mean to ask about Administrative Distance vs. Feasible Distance or did you mean to ask about Advertised Distance vs. Feasible Distance?
