What field content is used by ICMPv6 to determine that a packet has expired?

  • TTL field
  • CRC field
  • Hop Limit field
  • Time Exceeded field

Explanation: ICMPv6 sends a Time Exceeded message if the router cannot forward an IPv6 packet because the packet expired. The router uses a hop limit field to determine if the packet has expired, and does not have a TTL field.
