By

default,

when

you

enable

IPv6

or

configure

any

other

valid

IPv6

address

on

an

interface,

the

ACE

automatically

creates

a

link

local

address

for

it.

Every

link

local

address

must

have

a

predefined

pr

efix

of

FE8

0::/10.

You

can

configure

onl

y

one

IPv6

link

local

address

on

a

n

interface.

This

address

always

has

the

pr

efix

of

64.

To

manually

configure

the

link

local

address,

enter

a

complete

IPv6

address

with

an

FE80::/10

prefix

in

this

field.

For

example,

enter

In

a

you

can

configure

an

local

address

for

the

standby

ACE.

You

can

configure

only

one

peer

link

local

address

on

an

interface.

To

configure

the

peer

link

local

address,

enter

a

complete

IPv6

address

with

an

FE80::/10

prefix

in

this

field.

Note

The

NS

Int

erval

The

ACE

sends

neighbor

solicitation

messages

through

ICMPv6

on

the

local

link

to

determine

the

IPv6

addresses

of

ne

arby

nodes

(hosts

or

routers).

You

can

configure

t

he

rate

at

which

the

ACE

sends

these

neighbor

solicitation

messages.

By

default,

the

interval

at

which

the

ACE

sends

NS

messages

for

DAD

default

is

1000

milliseconds

(msecs).

To

configure

the

interval,

enter

an

integer

from

1000

to

2147483647.

NS

Reachable

Time

The

neighbor

solicitation

reachable

time

is

the

time

period

in

milliseconds

during

which

a

host

considers

the

peer

is

reachable

after

a

reachability

confirmation

from

the

peer.

A

reachability

confirmation

can

include

neighbor

solicitation

or

advertisement,

or

any

upper

protocol

traffic.

By

default,

this

time

period

is

0

milliseconds.

To

configure

this

time,

enter

an

integer

from

0

to

3600000.

Retransmission

time

By

default,

the

advertised

retransmission

time

is

0

milliseconds.

To

configure

t

he

retransmission

ime,

enter

an

integer

from

0

to

By

default,
