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)

•
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 trace route 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.
