Given the output from the show ip eigrp topology command, which router is the feasible successor?

A.

B.

C.

D.

Explanation:
http://networklessons.com/eigrp/eigrp-neighbor-and-topology-table-explained/
To be the feasible successor, the Advertised Distance (AD) of that route must be less than the
Feasible Distance (FD) of the successor. From the output of the “show ip eigrp topology 10.0.0.5
255.255.255.255 we learn that the FD of the successor is 41152000. Now we will mention about the
answers, in the “Composite metric is (…/…)” statement the first parameter is the FD while the
second parameter is the AD of that route. So we need to find out which route has the second
parameter (AD) less than 41152000 -> only answer B satisfies this requirement with an AD of
128256.
