ICMPv6
ICMPv6 is supported on the platforms s z
ICMP for IPv6 combines the roles of ICMP, IGMP, and address resolution protocol (ARP) in IPv4. Like
IPv4, ICMPv6 provides functions for reporting delivery and forwarding errors, and provides a simple echo
service for troubleshooting. The FTOS implementation of ICMPv6 is based on RFC 2463.
Generally, 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 FTOS
ping and traceroute commands extend to support IPv6 addresses. These commands use ICMPv6
Type-2 messages.
