Router
Preference
Select the router preference (
Low

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.
