COMMAND USAGE
◆ All IPv6 addresses must be 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.
◆ 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.
