What field content is used by ICMPv6 to determine that a packet has expired?
Answer: The ICMPv6 works by sending the time Exceeded in case the router is not able to forward the IPV6 packets and the reason might be the expiration of the packets. The file which is used by ICMPv6 to find if the packet s expired is the hop limit filed.
You are well aware of the IPv4, ICMP (internet control message protocol) for it might be a good option because it provides important data about the network health, etc. ICMPv6 works with the IPv6, it gives the report in which the error is listed as if the packet process is not complete and also sends the message of the network status.
Consider if the router didn’t send the packets forward because of their size which makes it difficult to send on other networks, then the ICMP message is sent to the source host. The host process the ICMP message to check the adjustable size of the packet and resend the information. Another function of the ICMP is diagnostic, like the well-known ping which uses the Echo request and replies to check the node availability.
As compared to the ICMPv4 and ICMPv6 is much better because it has new features and functions, such as the IGMP (internet group, management protocol) whose work is to maintain the membership of the multicast group with the IPV4.
Ip work is to move the data from node to node, but for efficient work, another feature includes whose work is error report, router discovery, etc, while In IPv6 all of these functions are carried out by ICMPv6.ICMPv6 gives the framework for MLD (multicast listener discovery) and neighbor discovery. There are two types of ICMPv6 message format:
