From DHCPv6
Select this to have the Zyxel Device indicate to hosts to obtain network settings (such as
prefix and DNS settings) through DHCPv6.

Configuration
From DHCPv6
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.
Router
Preference
Select the router preference (
Low
,
Medium
or
High
) for the interface. The interface 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.
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 Zyxel Device discards
the packet and sends an error message to the sender to inform this.
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.
