Enabling IPv6 on an interface
Predefined
address
book
objects
already
exist
for
each
Ethernet
interface.
To
enable
IPv6
on
an
interface,
an
IPv6
address
and
network
(prefix)
must
be
added
to
the
associated
address
book
object.
This
is
done
specifying
a
comma
‐
separated
list
of
the
IPv4
address
and
the
IPv6
address
for
the
interface.
Note:
A
maximum
of
six
IPv4
and
six
IPv6
addresses
can
be
assigned
to
a
single
Ethernet
interface.
Addresses
in
excess
of
this
will
be
ignored.
The
networks
configured
on
an
interface
for
each
of
the
IP
addresses
can
be
different
from
each
other
(all
the
IPv4
or
IPv6
addresses
do
not
have
to
come
from
the
same
network).
If
an
IPv6
address
and
network
are
not
assigned,
IPv6
packets
arriving
at
the
interface
are
always
dropped.
Example: Enabling IPv6 on an interface
Assume
that
an
IPv6
address
and
network
have
to
be
associated
with
the
sfp1
interface
and
that
interface
already
has
the
IPv4
address
10.15.0.50
and
network
10.15.0.0/24
.
Now
add
the
single
IPv6
address
2001:DB8::1
from
the
network
2001:DB8::/32
to
the
address
object.
Device:/>
set
Address
IPAddress
sfp1_net
Address=10.15.0.0/24,2001:DB8::/32
Device:/>
set
Address
IPAddress
sfp1_ip
Address=10.15.0.50,2001:DB8::1
Tip:
When
using
the
CLI
set
Address
IPAddress
command,
you
can
append
a
new
IP
address
value
to
any
existing
values.
All
the
existing
values
can
be
displayed
by
typing
a
period
(“.”)
followed
by
a
tab
after
Address=
.
You
can
then
type
a
comma
(“,”)
followed
by
the
new
address
to
be
added
to
the
list.
Interface routes are added automatically
When
an
IPv6
address
and
network
are
assigned
to
an
Ethernet
interface
(both
are
required),
an
IPv6
route
for
that
interface
should
be
added
to
the
main
routing
table.
The
route
is
added
provided
the
automatic
route
creation
for
the
interface
is
enabled
(it
is
enabled
by
default).
Rules and routes can mix IPv4 and IPv6
There
is
no
requirement
for
the
SEG
to
have
separate
IP
rules
or
routes
that
refer
to
IPv4
and
IPv6
address
objects.
It
is
valid
to
use
an
IPAddress
that
combines
IPv4
and
IPv6
addresses
in
a
single
route
or
a
single
IP
rule.
However,
an
IP
rule
that
has
only
IPv4
as
its
source
and
only
IPv6
as
its
destination
will
not
have
any
useful
function.
