Think of a wildcard mask as the inverse of a subnet mask. The inverse of subnet mask 255.255.255.252 is 0.0.0.3. To calculate the inverse of the subnet mask, subtract the subnet mask from 255.255.255.255:

255.255.255.255 
- 255.255.255.224
Subtract the subnet mask

EIGRP uses the following values in its composite metric to calculate the preferred path to a network:
Bandwidth	(10,000,000/bandwidth)*256
Delay
Reliability
Load

9.4.1 DUAL Concepts
DUAL uses several terms which will be discussed in more detail throughout this section:
(next hop) Successor	A successor is a neighboring router that is used for packet forwarding and is the least-cost route to the destination network.
(shown in routing table) Feasible Distance (FD)	Feasible distance (FD) is the lowest calculated metric to reach the destination network.

Reported Distance (RD) or Advertised Distance (AD)	the total dsitance (metric) reported by a neighbor to the destination
(backup candidate) Feasible Successor (FS)	A feasible successor (FS) is a neighbor who has a loop-free backup path to the same network as the successor by satisfying the feasibility condition. 
Feasible Condition or Feasibility Condition (FC)	
The feasibility condition (FC) is met when a neighbor's reported distance (RD) to a network is less than the local router's feasible distance to the same destination network.
