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.

Syntax

ipv6 address ipv6-address link-local

no ipv6 address [ipv6-address link-local]

ipv6-address - The IPv6 address assigned to the interface.

Default Setting

No IPv6 addresses are defined

Command Mode

Interface Configuration (VLAN)

Command Usage

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.

Example

This example assigns a link-local address of FE80::269:3EF9:FE19:6779 to VLAN 1. Note that the
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

Link-local address:

FE80::269:3EF9:FE19:6779/64

Global unicast address(es):

2001:DB8::1:2E0:CFF:FE00:FD/64, subnet is 2001:DB8::1:0:0:0:0/64[EUI]

2001:DB8:2222:7272::72/96, subnet is 2001:DB8:2222:7272::/96[EUI]
