A user executes a traceroute over IPv6. At what point would a router in the path to the destination device drop the packet?

  • when the value of the Hop Limit field reaches 255
  • when the value of the Hop Limit field reaches zero
  • when the router receives an ICMP time exceeded message
  • when the target host responds with an ICMP echo reply message
    Answers Explanation & Hints:

    When a traceroute is performed, the value in the Hop Limit field of an IPv6 packet determines how many router hops the packet can travel. Once the Hop Limit field reaches a value of zero, it can no longer be forwarded and the receiving router will drop the packet.
