Enable RADVD
Select this to have the GPON Device 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.
Enable ULA Prefix
Advertisement
Select this to send Unique Local IPv6 Unicast Addresses (ULA) advertisement
messages to the LAN hosts.
Enable RADVD Send
DNSv6Server
Select this to have the GPON Device include the DNSv6 server address in the router
advertisement messages it sends to the LAN hosts.
Randomly Generate Select this to automatically create a LAN IPv6 address prefix.
Statically Configure
Select this to send a fixed LAN IPv6 address prefix.
Prefix
: enter the IPv6 prefix and length the GPON Device uses to generate the LAN
IPv6 address. The prefix length specifies how many most significant bits (starting
from the left) in the address compose the network address. This field displays the
bit number of the IPv6 subnet mask.
Preferred Life Time (hour)
: enter the preferred lifetime for the prefix. -1 means
no time limit.
Valid Life Time (hour)
: enter the valid lifetime for the prefix. Set this greater than
or equal to the preferred life time. -1 means no time limit.
Enable MLD Snooping
Select this to have the GPON Device check Multicast Listener Discovery (MLD)
packets to learn the multicast group membership. This helps reduce multicast
traffic.
Standard Mode
Select this to have the GPON Device forward multicast packets to a port that joins
the multicast group and broadcast unknown multicast packets from the WAN to all
LAN ports.
Blocking Mode
Select this to have the GPON Deviceblock all unknown multicast packets from the
WAN.
Enable MLD LAN to LAN
Multicast
Select this to allow MLD multicast traffic to travel between the LAN ports.
