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 CTRL_C to break
During the execution of the command, press Ctrl+C to abort the tracert
operation.
1 1.1.1.2 (1.1.1.2) 673 ms
425 ms 30 ms
Probe result of the probe packets whose TTL is 1, including the following:
• Domain name (or IP address, if the domain name is not configured) of the
first hop.
• The round-trip time of the 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.
