traceroute to 1.1.2.2(1.1.2.2)
Display the route that the IP packets traverse from the current device to the
device whose IP address is 1.1.2.2.
hops at most
Maximum number of hops of the probe packets, which can be set by the -m
keyword.
bytes each packet Number of bytes of a probe packet.

operation.

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, carrying 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 in
another label stack.
tracert ipv6
Use tracert ipv6 to display the path that the IPv6 packets traverse from source to destination.
Syntax
tracert ipv6 [ -f first-hop | -m max-hops | -p port | -q packet-number | -vpn-instance vpn-instance-name
| -w timeout ] * host

Parameters
-f first-hop: Specifies the first hoplimit (the allowed number of hops for the first packet). The first-hop
argument is in the range of 1 to 255. The default value is 1. The first hoplimit must be less than the value
of the max-hops argument.
-m max-hops: Specifies the maximum number of hops allowed for a packet. The max-hops argument is
in the range of 1 to 255. The default value is 30. It must be greater than the value of the first-hop
argument.
-p port: Specifies the UDP port number of the destination. The port argument is in the range of 1 to 65535.
The default value is 33434. It is unnecessary to modify this option.
-q packet-number: Specifies the number of probe packets sent each time. The packet-number argument
is in the range of 1 to 65535. The default value is 3.
