Which field in an IPv6 packet is used by the router to determine if a packet has expired and should be dropped?
- Hop Limit
- Address Unreachable
- No Route to Destination
Explanation: ICMPv6, like IPv4, sends a Time Exceeded message if the router cannot forward an IPv6 packet because the packet has expired. However, the IPv6 packet does not have a TTL field. Instead, it uses the Hop Limit field to determine if the packet has expired.
