DESCRIPTION
Select this to have the Device send router advertisement messages to the LAN hosts.
Router advertisement is a response to a router solicitation or a periodical multicast
advertisement from a router to advertise its presence and other parameters, such as
IPv6 prefix and DNS information.
Router solicitation is a request from a host to locate a router that can act as the
default router and forward packets.
Note: The LAN hosts neither generate global IPv6 addresses nor communicate with
other networks if you disable this feature.
Select this to have the Device obtain the M/O (Managed/Other) flag setting from the
service provider or uplink router.
Select this to specify the M/O flag setting manually.
Select this to have the Device indicate to hosts to obtain network settings (such as
prefix and DNS settings) through DHCPv6.
Clear this to have the Device indicate to hosts that DHCPv6 is not available and they
should use the prefix in the router advertisement message.
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.
Select this to have the Router Advertisement messages the VDSL Router
sends specify the allowed interval between Router Advertisement messages.
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.
Enter the time in seconds that hosts should consider the Device to be the default
router. Possible values for this field are 0-9000.
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.
Enter the time in milliseconds that can elapse before a neighbor is detected. Possible
values for this field are 0-3600000.
Enter the time in milliseconds between neighbor solicitation packet retransmissions.
Possible values for this field are 1000-4294967295.
Enter the time in seconds between router advertisement messages. Possible values for
this field are 4-1800.
Select this to have the Device obtain the MTU setting from the service provider or
uplink router.
Select this to specify the MTU manually.
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.
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.
