Refer to the exhibit.
Which path is selected as best path?
A.
path 1, because it is learned from IGP
B.
path 1, because the metric is the lowest
C.
path 2, because it is external
D.
path 2, because it has the higher router ID
Explanation:
Metrics is a property of a route in computer networking, consisting of any value used by a routing
protocol to determine whether one particular route should be chosen over another. The routing
table stores only the best possible routes, while link-state or topological databases may store all
other information as well. For example, Routing Information Protocol uses hopcount (number of
hops) to determine the best possible route. The route will go in the direction of the gateway with
the lowest metric (default gateway).
