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.

DHCPv6 Configuration IPv6 DNS 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. IPv6 DNS Server1 Enter the first DNS server IPv6 address the ZyXEL Device passes to the DHCP clients. IPv6 DNS Server2 Enter the second DNS server IPv6 address the ZyXEL Device passes to the DHCP clients.
