4 to 6 Tunneling
To configure 4-to-6 tunneling:
STEP 1
Select
Networking
>
IPv6
>
Tunneling
.
STEP
2
In the 4 to 6 Tunneling field, check the Enable box.
STEP
3
Enter the local WAN IPv6 address on the device.
STEP
4
Enter the remote IPv6 address, or the IP address of the remote endpoint.
STEP
5
Click
Save
.
Viewing IPv6 Tunnel Status
To view IPv6 tunnel status:
STEP 1
Choose
Networking
>
IPv6
>
IPv6 Tunnels Status
.
STEP

to display the most up-to-date information.
This page displays information about the automatic tunnel set up through the
dedicated WAN interface. The table shows the name of tunnel and the IPv6
address that is created on the device.
Configuring Router Advertisement
The Router Advertisement Daemon (RADVD) on the device listens for router
solicitations in the IPv6 LAN and responds with router advertisements as required.
This is stateless IPv6 auto-configuration, and the device distributes IPv6 prefixes
to all nodes on the network.
To configure the RADVD:
STEP 1
Choose
Networking
>
IPv6
>
Router Advertisement
.
STEP
2
Enter this information:
RADVD Status
Check
Enable
to enable RADVD.

Advertise Mode
Select one of the following modes:
Unsolicited Multicast
—Send Router
Advertisements (RAs) to all interfaces belonging to
the multicast group.
Unicast only
—Restrict advertisements to
well-known IPv6 addresses only (RAs are sent to
the interface belonging to the known address only).
Advertise Interval
Advertise interval (4–1800) for the
Unsolicited
Multicast
. The default is 30. The advertise interval
is a random value between the Minimum Router
Advertisement Interval (MinRtrAdvInterval) and
Maximum Router Advertisement Interval
(MaxRtrAdvInterval).
MinRtrAdvInterval = 0.33 * MaxRtrAdvInterval
RA Flags
Check
Managed
to use the administered/stateful
protocol for address auto configuration.
Check
Other
to use the administered/stateful
protocol of other, non-address information auto
configuration.
Router Preference
Choose
low
,
medium
, or
high
from the drop-down
menu. The default is medium.
The router preference provides a preference
metric for default routers. The low, medium, and
high values are signaled in unused bits in RA
messages. This extension is backward compatible,
both for routers (setting the router preference
value) and hosts (interpreting the router preference
value). These values are ignored by hosts that do
not implement router preference. This feature is
useful if there are other RADVD-enabled devices
on the LAN.

Configuring Advertisement Prefixes
To configure the RADVD available prefixes:
STEP 1
Choose
Networking
>
IPv6

Advertisement Prefixes
.
STEP
2
Click
Add Row
.
STEP
3
Enter this information:
MTU
MTU size (0 or 1280 to 1500). The default is 1500
bytes.
The maximum transmission unit (MTU) is the size of
the largest packet that can be sent over the
network. The MTU is used in RAs to ensure all
nodes on the network use the same MTU value
when the LAN MTU is not well-known.
Router Life Time
Router lifetime value or the time in seconds that the
advertisement messages exists on the route. The
default is 3600 seconds.
IPv6 Prefix Type
Choose one of the following types:
6to4
—Allows IPv6 packets to be transmitted over
an IPv4 network. It is used when an end user wants
to connect to the IPv6 Internet using their existing
IPv4 connection
Global/Local
—A locally unique IPv6 address that
you can use in private IPv6 networks or a globally
unique IPv6 Internet address.

SLA ID
If you choose
6to4
as the IPv6 prefix type, enter
the Site-Level Aggregation Identifier (SLA ID).
The SLA ID in the 6to4 address prefix is set to the
interface ID of the interface on which the
advertisements are sent.
IPv6 Prefix
If you choose
Global/Local
as the IPv6 prefix type,
enter the IPv6 prefix. The IPv6 prefix specifies the
IPv6 network address.
IPv6 Prefix Length
If you choose
Global/Local
as the IPv6 prefix type,
enter the prefix length. The prefix length variable is
a decimal value that indicates the number of
contiguous, higher-order bits of the address that
make up the network portion of the address.
Prefix Lifetime
Prefix lifetime, or the length of time over which the
requesting router is allowed to use the prefix.
