IPv6 Interface
– 630 –
ipv6-address - The IPv6 address of a neighbor device. You can
specify either a link-local or global unicast address formatted
according to RFC 2373 “IPv6 Addressing Architecture,” using 8
colon-separated 16-bit hexadecimal values. One double colon may
be used in the address to indicate the appropriate number of zeros
required to fill the undefined fields.
host-name - A host name string which can be resolved into an IPv6
address through a domain name server.
failure-count - The maximum number of failures before which the
trace route is terminated. (Range: 1-255)
Default Setting
Maximum failures: 5
Command Mode
Privileged Exec
Command Usage
◆ Use the traceroute6 command to determine the path taken to reach a
specified destination.
◆
The same link-local address may be used by different interfaces/nodes in
different zones (RFC 4007). Therefore, when specifying a link-local
address, include zone-id information indicating the VLAN identifier after
the % delimiter. For example, FE80::7272%1 identifies VLAN 1 as the
interface from which the ping is sent.
◆
A trace terminates when the destination responds, when the maximum
timeout (TTL) is exceeded, or the maximum number of hops is exceeded.
◆ The traceroute command first sends probe datagrams with the TTL value
set at one. This causes the first router to discard the datagram and return
an error message. The trace function then sends several probe messages
at each subsequent TTL level and displays the round-trip time for each
message. Not all devices respond correctly to probes by returning an
“ICMP port unreachable” message. If the timer goes off before a response
is returned, the trace function prints a series of asterisks and the “Request
Timed Out” message. A long sequence of these messages, terminating
only when the maximum timeout has been reached, may indicate this
problem with the target device.
Example
Console#traceroute6 FE80::2E0:CFF:FE9C:CA10%1
Press "ESC" to abort.
Traceroute to FE80::2E0:CFF:FE9C:CA10%1/64, 30 hops max, timeout is 3
seconds, 5 max failure(s) before termination.
