If no metric is specified for the routes being redistributed into IS-IS, what metric value is assigned
to the routes?

A.
20

B.
10

C.
0

D.
1

Explanation:
The IS-IS metric must be between 1 and 63. There is no default-metric option in IS-IS—you should
define a metric for each protocol. If no metric is specified for the routes being redistributed into ISIS, a metric value of 0 is used by default.
