ping6 { ipv6-address | host-name } [ count count ] [ size size ]
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.
count - Number of packets to send. (Range: 1-16)
size - Number of bytes in a packet. (Range: 48-18024 bytes)
The actual packet size will be eight bytes larger than the size
specified because the router adds header information.

◆
Use the ping6 command to see if another site on the network can be
reached, or to evaluate delays over the path.
◆
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.
◆
When pinging a host name, be sure the DNS server has been enabled
(see
page 1034 ). If necessary, local devices can also be specified in the
DNS static host table (see page 1036 ).
◆
When using ping6 with a host name, the router first attempts to resolve
the alias into an IPv6 address before trying to resolve it intoan IPv4
address.
