Managed config
flag on
Select this to have the Device indicate to hosts to obtain network settings (such as
prefix and DNS settings) through DHCPv6.

should use the prefix in the router advertisement message.
Other config flag
on
Select this to have the Device indicate to hosts to obtain DNS information through
DHCPv6.
Clear this to have the Device indicate to hosts that DNS information is not available in
this network.
Advertisement
interval option on
Select this to have the Router Advertisement messages the VDSL Router
sends specify the allowed interval between Router Advertisement messages.
Hop limit Enter the maximum number of network segments that a packet can cross before
reaching the destination. When forwarding an IPv6 packet, IPv6 routers are required
to decrease the Hop Limit by 1 and to discard the IPv6 packet when the Hop Limit is 0.
Possible value for this field are 0-255.
Router Lifetime Enter the time in seconds that hosts should consider the Device to be the default
router. Possible values for this field are 0-9000.
Router Preference Select the router preference (Low, Medium or High) for the Device. The Device
sends this preference in the router advertisements to tell hosts what preference they
should use for the Device. This helps hosts to choose their default router especially
when there are multiple IPv6 router in the network.
Note: Make sure the hosts also support router preference to make this function work.
Reachable Time (ms) Enter the time in milliseconds that can elapse before a neighbor is detected. Possible
values for this field are 0-3600000.
Retrans Timer (ms) Enter the time in milliseconds between neighbor solicitation packet retransmissions.
Possible values for this field are 1000-4294967295.
RA Interval Enter the time in seconds between router advertisement messages. Possible values for
this field are 4-1800.

uplink router.
Manual Select this to specify the MTU manually.
MTU The Maximum Transmission Unit. Type the maximum size of each IPv6 data packet, in
bytes, that can move through this interface. If a larger packet arrives, the Device
divides it into smaller fragments.
DAD attempts Specify the number of DAD (Duplicate Address Detection) attempts before an IPv6
address is assigned to the Device LAN interface. Possible values for this field are 1-7.
DHCPv6
DHCPv6 Server Use this field to Enable or Disable DHCPv6 server on the Device.

network. Alternatively, select Manual and specify the DNS servers’ IPv6 address in the
fields below.
Primary DNS This field is available if you choose Manual as the DNSv6 mode. Enter the first DNS
server IPv6 address the Device passes to the DHCP clients.
Secondary DNS This field is available if you choose Manual as the DNSv6 mode. Enter the second DNS
server IPv6 address the Device passes to the DHCP clients.
