Address

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

EUI-64

box

to

specify

that

the

low

order

64

bits

are

automatically

generated

in

the

IEEE

64-bit

Extended

Unique

Identifier

(EUI-64)

format

specified

in

RFC

2373.

To

use

EUI-64,

the

Prefix

Length

field

must

be

less

than

or

equal

to

64

and

the

host

segment

must

be

all

zeros.

Note

The

IPv6

peer

global

address

must

be

unique

across

multiple

contexts

on

a

shared

VLAN.

Enter

an

If

you

use

the

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.
