To
configure

an

IPv6

peer

global

address,

enter

a

complete

IPv6

address

with

a

prefix

of

2000::/3
to
3fff::/3.

For

example,

enter

2001:DB8:1::0.
Check
the

are

automatically

generated

in

the
IEEE

format

specified

in

RFC

2373.

To

use

EUI-64,
the
Prefix

field

must

be

less

than

or

equal

to

64

and

the

host

segment

must

be

all

zeros.
Note
The

must

be
unique
across

multiple

on
a

type.

A

unique

local

address

is

an

optional

IPv6

unicast

address

that
is
used

for

local

communication

within

an

organization

and

it

is

similar

to

a

private

IPv4

address
(for
example,

10.10.2.1).

Unique

local

addresses

have

a

global

scope,

but

they

are

not

routable
on
t

he

internet,

and

they

are

assigned

by

a

ce

ntral

authority.

All

uni

que

local

addresses

have

a
predefined
prefix

of

FC00::/7.

You

can

configure

only

one

IPv6

unique

local

address

on

an
interface.
