6.6 Technical Reference

The following section contains additional technical information about the Device features described
in this chapter.
P-870HNU-51b User's Guide
DESCRIPTION
An IPv6 prefix length specifies how many most significant bits (start from the
left) in the address compose the network address.
This field displays the bit number of the IPv6 subnet mask.
Select Enable to have the 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.
Select this option to have the Device act as a DHCP server to assign and pass
DNS server information to its DHCP clients.
Select this option to activate MLD snooping on the Device. This allows the
Device to check MLD packets passing through it and learn the multicast group
membership. It helps reduce multicast traffic.
Select this to have the Device forward multicast packets to a port that joins the
multicast group and broadcast unknown multicast packets from the WAN to all
LAN ports.
Select this to have the Device block all unknown multicast packets from the
WAN.
Click Apply to save your changes back to the Device.
