Field 1 1.1.1.2 673 ms 425 ms 30 ms MPLS Label=100048 Exp=0 TTL=1 S=1 Description Probe result of the probe packets whose TTL is 1, including the IP address of the first hop and the roundtrip time of three probe packets. The number of packets that can be sent in each probe can be set through the -q keyword. ICMP timeout packets on an MPLS network, carry MPLS label information: • Label-Label value that is used to identify a forwarding equivalence class (FEC). • Exp-Reserved, usually used for class of service (CoS). • TTL-TTL value. • S-MPLS supports multiple levels of labels. Value 1 indicates that the label is at the bottom of the label stack, and value 0 indicates that the label is not at the bottom of the label stack. tracert ipv6 Syntax tracert ipv6 [ -f first-ttl | -m max-ttl | -p port | -q packet-number | -tos tos| -vpn-instance vpn-instance-name | -w timeout ] * host View Any view Default level 0: Visit level Parameters -f first-ttl: Specifies the first TTL, or, the allowed number of hops for the first packet. It is in the range of 1 to 255 and defaults to 1, and must be less than the maximum TTL. -m max-ttl: Specifies the maximum TTL (the maximum allowed number of hops for a packet). It is in the range of 1 to 255 and defaults to 30, and must be greater than the first TTL. -p port: Specifies the UDP port number of the destination, which is in the range of 1 to 65535 and defaults to 33434. It is unnecessary to modify this option. -q packet-number: Specifies the number of probe packets sent each time, which is in the range of 1 to 65535 and defaults to 3. -w timeout: Specifies the timeout time of the reply packet of a probe packet, which is in the range of 1 to 65535 milliseconds and defaults to 5000 milliseconds. host: Specifies the IPv6 address or host name of the destination, a string of 1 to 46 characters. -tos tos: Specifies the ToS value for an IPv6 tracert packet, which is in the range of 0 to 255 and defaults to 0. -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. Description Use tracert ipv6 to view the path the IPv6 packets traverse from source to destination. 9

1.1.1.2 673 ms 425 ms 30 ms
Probe result of the probe packets whose TTL is 1, including the IP
address of the first hop and the roundtrip time of three probe packets.
The number of packets that can be sent in each probe can be set
through the
-q
keyword.
MPLS Label=100048 Exp=0 TTL=1
S=1
ICMP timeout packets on an MPLS network, carry MPLS label
information:
•
Label
—Label value that is used to identify a forwarding
equivalence class (FEC).
•
Exp
—Reserved, usually used for class of service (CoS).
•
TTL
—TTL value.
•
S
—MPLS supports multiple levels of labels. Value 1 indicates that
the label is at the bottom of the label stack, and value 0 indicates
that the label is not at the bottom of the label stack.

Parameters
-f
first-ttl
: Specifies the first TTL, or, the allowed number of hops for the first packet. It is in the range of 1
to 255 and defaults to 1, and must be less than the maximum TTL.
-m
max-ttl
: Specifies the maximum TTL (the maximum allowed number of hops for a packet). It is in the
range of 1 to 255 and defaults to 30, and must be greater than the first TTL.
-p
port
: Specifies the UDP port number of the destination, which is in the range of 1 to 65535 and
defaults to 33434. It is unnecessary to modify this option.
-q
packet-number
: Specifies the number of probe packets sent each time, which is in the range of 1 to
65535 and defaults to 3.
-w
timeout
: Specifies the timeout time of the reply packet of a probe packet, which is in the range of 1
to 65535 milliseconds and defaults to 5000 milliseconds.
host
: Specifies the IPv6 address or host name of the destination, a string of 1 to 46 characters.
-tos
tos
: Specifies the ToS value for an IPv6 tracert packet, which is in the range of 0 to 255 and defaults
to 0.
-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.
