– 1669 –
ipv6 address
link-local
This command configures an IPv6 link-local address for an interface and
enables IPv6 on the interface. Use the no form without any arguments to
remove all manually configured IPv6 addresses from the interface. Use the
no form with a specific address to remove it from the interface.

◆
The specified address must be 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. And
the address prefix must be in the range of FE80~FEBF.
◆
The address specified with this command replaces a link-local address
that was automatically generated for the interface.
◆
You can configure multiple IPv6 global unicast addresses per interface,
but only one link-local address per interface.
◆
If a duplicate address is detected, a warning message is sent to the
console.

XAMPLE
This example assigns a link-local address of FE80::269:3EF9:FE19:6779 to
VLAN 1. Note that a prefix in the range of FE80~FEBF is required for link-
local addresses, and the first 16-bit group in the host address is padded
with a zero in the form 0269.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address FE80::269:3EF9:FE19:6779 link-local
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled.
