Show - Planet Networking & Communication WGSW-50040 Configuration Manual

of the Traceroute6 under IPv6 is the same as that under IPv4, which adopts the hop limit field of the ICMPv6
and IPv6 header. First, Traceroute6 sends an IPv6 datagram (including source address, destination address
and packet sent time) whose HOPLIMIT is set to 1. When first route on the path receives this datagram, it
minus the HOPLIMIT by 1 and the HOPLIMIT is now 0. So the router will discard this datagram and returns
with a 「ICMPv6 time exceeded」 message (including the source address of the IPv6 packet, all content in the
IPv6 packet and the IPv6 address of the router). Upon receiving this message, the Traceroute6 sends another
datagram of which the HOPLIMIT is increased to 2 so to discover the second router. Plus 1 to the HOPLIMIT
every time to discover another router, the Traceroute6 repeat this action till certain datagram reaches the
destination.
Traceroute6 Options and explanations of the parameters of the Traceroute6 command please refer to
