For ICMP, the trace file command in ICMP Router Configuration Mode specifies a file for tracing of all ICMP events. Because the Host B is down, the router will send an ICMP Destination host unreachable message to Host A, informing it that the destination host is unreachable, e.g. The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. The Internet Control Message Protocol (ICMP), is a very popular protocol and actually part of an Internet Protocol (IP) implementation. So ICMP processing can be viewed as occurring parallel to, or as part of, IP processing. These versions are IPv4 and IPv6.
