Table 3 Command output

Field Descri

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 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.

press escape sequence to

break

During the execution of the command, press the break key sequence

combination (Ctrl+C by default) to abort the tracert operation.

1 1.1.1.2 673 ms 425 ms 30

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.
