C.
It prevents regular update messages from reinstating a route that has just come up.

AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Another way to avoid problems caused by inconsistent updates and to stop network loops is route poisoning. When a network goes down, the distance-vector routing protocol initiates route poisoning by advertising the network with a metric of 16, or unreachable (sometimes referred to as infinite).
