Send RA
on
Select this to have the AMG1312-T Series 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 AMG1312-T Series indicate to hosts to obtain network settings
(such as prefix and DNS settings) through DHCPv6.
Clear this to have the AMG1312-T Series indicate to hosts that DHCPv6 is not available
and they should use the prefix in the router advertisement message.
Other
config flag
on
Select this to have the AMG1312-T Series indicate to hosts to obtain DNS information
through DHCPv6.

Select this to have the Router Advertisement messages the VDSL Router sends specify
the allowed interval between Router Advertisement messages.
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.
Possible value for this field are 0-255.
Router

Enter the time in seconds that hosts should consider the AMG1312-T Series to be the
default router. Possible values for this field are 0-9000.
Router
Preference
Select the router preference (Low, Medium or High) for the AMG1312-T Series. The
AMG1312-T Series sends this preference in the router advertisements to tell hosts what
preference they should use for the AMG1312-T Series. 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.
