Question

The ___ is the metric to a neighbor router plus that neighbor router's AD (Advertised Distance) to the destination network.

a) Successor metric
b) Feasible Distance (FD)
c) Reported Distance (RD)
d) Composite Metric

Answer 1

Option (B), The metric that combines the neighbor router metric with its Advertised Distance (AD) to the destination network is known as the Feasible Distance (FD). It is essential in routing protocols like EIGRP for determining the best path to a destination network.

Step-by-step explanation:

The metric you're asking about is known as the Feasible Distance (FD). This is a term commonly used in routing protocols, particularly in Enhanced Interior Gateway Routing Protocol (EIGRP), which is used to help manage routing and data transmission paths within an autonomous system. The Feasible Distance is calculated as the metric to a neighbor router plus that neighbor router's Advertised Distance (AD) to the destination network. The result is the metric that EIGRP would use for the routing table if this path becomes the one selected to reach a specific destination network.
