-vpn-instance
vpn-instance-name
: Specifies the MPLS L3VPN to which the destination belongs, where
vpn-instance-name
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 of the reply packet of a probe packet, which ranges from 1 to
65535 milliseconds and defaults to 5000 milliseconds.
host
: IPv6 address or host name of the destination, which is a string of 1 to 46 characters.
Usage guidelines
In the event of network failure, you can use the
tracert
command to determine the failed nodes.
Output from the
tracert
ipv6
command includes IPv6 addresses of all the Layer 3 devices the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message (probably 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
.
Examples
# View the path the packets traverse from source to destination with IPv6 address 2001::1.
<Sysname> tracert ipv6 2001::1
traceroute to 2001::1 30 hops max,60 bytes packet, press CTRL_C to break
1 2001::1 3 ms <1 ms 19 ms
# View the path the packets traverse from source to destination with IPv6 address 2001::1 in VPN 1.
<Sysname> tracert ipv6 –vpn-instance vpn1 2001::1
traceroute to 2001::1 30 hops max,60 bytes packet, press CTRL_C to break
1 2001::1 3 ms <1 ms 19 ms
