Question 20

Which of the following statements explains the behavior of the ICMP redirect function? (Choose two)

When a router receives data on the interface via which the same data needs to be forwarded, and the source is on the same segment as the next hop, an ICMP redirect message will be sent by the router to the source.

When a router receives data on an interface, and the router's IP address matches the destination IP of the data, an ICMP redirect message will be sent by the router to the source.

When a router receives data on the interface via which the same data needs to be forwarded, and the source is on the same segment as the next hop, an ICMP Redirect message will be sent by the source to the router.

When a router receives data on the interface via which the same data needs to be forwarded, and the source is on a different segment from the next hop, an ICMP redirect message will be sent by the router to the source

Correct Answer: A, D

When a router receives data on the same interface via which the data needs to be forwarded, and if the source is on the same segment as the next hop, the router sends an ICMP redirect message to the source. Additionally, if the source is on a different segment from the next hop, this will still prompt an ICMP redirect message from the router to the source. These conditions ensure that the data takes the most efficient path, avoiding unnecessary routing loops.
