What is route poisoning?
It sends back the protocol received from a router as a poison pill, which stops the regular updates.
It is information received from a router that can't be sent back to the originating router.
It prevents regular update messages from reinstating a route that has just come up.
It describes when a router sets the metric for a downed link to infinity.
Answer: Option
Explanation:
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).

Route poisoning is a method that prevents a certain network from sending data packets to a path destination that has already become invalid. This is done when a distance vector routing protocol sees an invalid route or one with large routing loops.
