tion
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 max
Maximum number of hops of the probe packets, which can be set
through the -m keyword.
bytes packet Number of bytes of a probe packet.
press CTRL_C to break
During the execution of the command, you can press Ctrl+C to abort
the tracert operation.
1 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.
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.
tracert ipv6
Use tracert ipv6 to view the path the IPv6 packets traverse from source to destination.
Syntax

Parameters
-f first-ttl: Specifies the first TTL, or, the allowed number of hops for the first packet. The value range is 1
to 255, and the default is 1. The value must be less than the maximum TTL.
-m max-ttl: Specifies the maximum TTL, or, the maximum allowed number of hops for a packet. The value
range is 1 to 255, and the default is 30. The value must be greater than the first TTL.
