ICMPv6 ICMP for IPv6 (ICMPv6) combines the roles of ICMP, IGMP and ARP in IPv4. Like IPv4, it provides functions for reporting delivery and forwarding errors, and provides a simple echo service for troubleshooting. The implementation of ICMPv6 is based on RFC 4443. ICMPv6 uses two message types: • Error reporting messages indicate when the forwarding or delivery of the packet failed at the destination or intermediate node. These messages include Destination Unreachable, Packet Too Big, Time Exceeded and Parameter Problem messages. • Informational messages provide diagnostic functions and additional host functions, such as Neighbor Discovery and Multicast Listener Discovery. These messages also include Echo Request and Echo Reply messages. The ping and traceroute commands extend to support IPv6 addresses. These commands use ICMPv6 Type-2 messages. Path MTU Discovery IPv6 path maximum transmission unit (MTU), in accordance with RFC 1981, defines the largest packet size that can traverse a transmission path without suffering fragmentation. Path MTU for IPv6 uses ICMPv6 Type-2 IPv6 Routing 570
