The link between CE1 and PE1 has a history of flapping. To avoid the impact that flapping causes to the network, you decide to use route damping. Which statement is correct in this scenario?
A.
Dampening is enabled on interfaces.
B.
Dampened routes decay at a sliding rate known as half-life.
C.
Routes become dampened when the configured max-suppress value is reached.
D.
Dampened routes become active when their figure of merit drops below the reuse value.
Answer is D

Reuse merit
Figure-of-merit value below which a suppressed route can be used again. A suppressed route becomes reusable when its figure-of-merit value decays to a value below a reuse threshold, and the route once again is considered usable and can be installed in the forwarding table and exported from the routing table.
B is correct, however D is also correct in my opinion. A suppressed route becomes reusable when its figure-of-merit value decays to a value below a reuse threshold, and the route once again is considered usable and can be installed in the forwarding table and exported from the routing table.
D : Figure-of-merit value below which a suppressed route can be used again. A suppressed route becomes reusable when its figure-of-merit value decays to a value below a reuse threshold, and the route once again is considered usable and can be installed in the forwarding table and exported from the routing table.
