DHCPv6 Configuration
The
commands
described
in
this
chapter
perform
configuration
of
the
Dynamic
Host
Configuration
Protocol
for
IPv6
(DHCPv6)
on
the
SecureStack
C3.
Overview
DHCP
is
generally
used
between
clients
(for
example,
hosts)
and
servers
(for
example,
routers)
for
the
purpose
of
assigning
IP
addresses,
gateways,
and
other
networking
definitions
such
as
DNS,
NTP,
and/or
SIP
parameters.
However,
IPv6
natively
provides
for
auto
‐
configuration
of
IP
addresses
through
the
IPv6
Neighbor
Discovery
Protocol
(NDP)
and
the
use
of
Router
Advertisement
messages.
Thus,
the
role
of
DHCPv6
within
the
network
is
different
from
DHCPv4
in
that
it
is
less
relied
upon
for
IP
address
assignment.
DHCPv6
server
and
client
interactions
are
described
by
RFC
3315.
There
are
many
similarities
between
DHCPv6
and
DHCPv4
interactions
and
options,
but
the
messages
and
option
definitions
are
sufficiently
different.
There
is
no
migration
or
inter
‐
operability
from
DHCPv4
to
DHCPv6.
DHCPv6
incorporates
the
notion
of
the
stateless
server,
where
DHCPv6
is
not
used
for
IP
address
assignment
to
a
client.
Instead,
it
only
provides
other
networking
information
such
as
DNS,
NTP,
and/or
SIP
information.
The
stateless
server
behavior
is
described
by
RFC
3736,
which
simply
contains
descriptions
of
the
portions
of
RFC
3315
that
are
necessary
for
stateless
server
behavior.
In
order
for
a
router
to
drive
a
DHCPv6
client
to
utilize
stateless
DHCPv6,
the
“other
stateful
configuration”
option
must
be
configured
for
neighbor
discovery
on
the
corresponding
IPv6
router
interface.
This
in
turn
causes
DHCPv6
clients
to
send
the
DHCPv6
“Information
Request”
message
in
response.
A
DHCPv6
server
then
responds
by
providing
only
networking
definitions
such
as
DNS
domain
name
and
server
definitions,
NTP
server
definitions,
and/or
SIP
definitions.
* IPv6 Routing License Required *
IPv6 routing must be enabled with a license key in order to use this feature. If you have purchased an IPv6
routing license key, and have enabled routing on the device, you must activate your license as described in
the chapter entitled “Activating Licensed Features” in order
to enable the DHCPv6 configuration command
set. If you wish to purchase an IPv6 routing license, contact Enterasys Networks Sales.
