Use tracert ipv6 to display the path that the IPv6 packets traverse from source to destination.
tracert ipv6 [ -f first-hop | -m max-hops | -p port | -q packet-number | -t traffic-class | -vpn-instance
vpn-instance-name | -w timeout ] * host
Predefined user roles
-f first-hop: Specifies the TTL value of the first packet. The value range is 1 to 255, and the default is 1. The
value must be no greater than the value of the max-hops argument.
-m max-hops: Specifies the maximum number of hops allowed for a packet. The value range is 1 to 255,
and the default is 30. The value must be no smaller than the value of the first-hop argument.
-p port: Specifies an invalid UDP port of the destination. The value range is 1 to 65535, and the default
-q packet-number: Specifies the number of probe packets sent each time. The value range is 1 to 65535,
and the default is 3.
-t traffic-class: Specifies the traffic class value in an IPv6 tracert packet. The value range is 0 to 255, and
the default is 0.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination
is on the public network, do not specify this option.
-w timeout: Specifies the timeout time (in milliseconds) of the reply packet of a probe packet. The value
range is 1 to 65535, and the default is 5000.
host: Specifies the IPv6 address or host name of the destination. The host name is a case-insensitive string
of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore
(_), and dot (.).
After identifying network failure with the ping ipv6 command, you can use the tracert ipv6 command to
locate failed nodes.
The output of the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices that the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message (this can be because the destination is unreachable or sending ICMP
timeout/destination unreachable packets is disabled).
To abort the tracert operation during the execution of the command, press Ctrl+C.
