Usage
Refer
to
RFC
2461,
“Neighbor
Discovery
for
IP
Version
6,”
for
more
information
about
router
advertisements.
Router
advertisements
contain
a
list
of
prefixes
used
for
on
‐
link
determination
and/or
autonomous
address
configuration.
Flags
associated
with
the
prefixes
specify
the
intended
uses
of
a
particular
prefix.
Hosts
use
the
advertised
on
‐
link
prefixes
to
build
and
maintain
a
list
that
is
used
in
deciding
when
a
packet’s
destination
is
on
‐
link
or
beyond
a
router.
Hosts
can
use
the
advertised
autoconfiguration
prefixes
to
perform
autonomous
(stateless)
address
configuration,
if
stateless
configuration
is
allowed
(see
ipv6
nd
other
‐
config
‐
flag
).
The
no
form
of
this
command
removes
the
prefix
from
the
list
of
prefixes
advertised
in
router
advertisements
by
this
interface.

the
form
documented
in
RFC
4291,
with
the
address
specified
in
hexadecimal
using
16
‐
bit
values
between
colons.
The
prefix
length
is
a
decimal
number
indicating
the
number
of
high

order
contiguous
bits
of
the
address
that
comprise
the
network
portion
of
the
address.
valid

infinite
(Optional)
Specifies
the
length
of
time
in
seconds
(relative
to
the
time
the
packet
is
sent)
that
the
prefix
is
valid
for
the
purpose
of
on
‐
link
determination.
The
lifetime
value
can
range
from
0
to

Specifying

means
that
the
prefix
is
always
valid.

remain
preferred.
The

can
range
from
0
to
