DESCRIPTION
Select this to have the ZyXEL 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 ZyXEL Device indicate to hosts to obtain network settings (such
as prefix and DNS settings) through DHCPv6.
Clear this to have the ZyXEL 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 ZyXEL Device indicate to hosts to obtain DNS information
through DHCPv6.
Clear this to have the ZyXEL Device indicate to hosts that DNS information is not
available in this network.
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 ZyXEL Device to be the
default router. Possible values for this field are 0-9000.
Select the router preference (Low, Medium or High) for the ZyXEL Device. The
ZyXEL Device sends this preference in the router advertisements to tell hosts what
preference they should use for the ZyXEL 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 ZyXEL 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 ZyXEL
Device divides it into smaller fragments.
Specify the number of DAD (Duplicate Address Detection) attempts before an IPv6
address is assigned to the ZyXEL Device LAN interface. Possible values for this field
are 1-7.
Configure the IPv6 DNS information the ZyXEL device passes to clients when it acts as
a DHCPv6 server. Select Auto if your ISP dynamically assigns DNS server information.
Select Manual to configure DNS server addresses manually.
Enter the first DNS server IPv6 address the ZyXEL Device passes to the DHCP clients.
Enter the second DNS server IPv6 address the ZyXEL Device passes to the DHCP
clients.
Enter the number of seconds a DHCPv6 client should wait before refreshing
information retrieved from DHCPv6.
