IPv6 Routing Commands 653
traceroute ipv6
Use the
traceroute ipv6
command in Privileged EXEC mode to discover the routes that packets
actually take when traveling to their destination through the network on a hop-by-hop basis.
Syntax
traceroute ipv6
ipv6-address
[
port
]
•
ipv6-address
—
Destination IPv6 address.
•
port
—
UDP port used as the destination of packets sent as part of the traceroute. This
port should be an unused port on the destination system. (Range: 0-65535)
Default Configuration
33434 is the default port value.
Command Mode
Privileged EXEC mode
User Guidelines
This command has no user guidelines.
Example
The following example discovers the packet routes on a hop-by-hop basis.
console#traceroute ipv6 2020:1::1
Tracing route over a maximum of 20 hops
1 * N * N * N
