DESCRIPTION
Select this option to automatically obtain an IPv6 network prefix from the service provider
or an uplink router.
Select this option to configure a fixed IPv6 address for the Device's LAN IPv6 address.
Note: This fixed address is for local hosts to access the Web Configurator only as the global
LAN IPv6 address might be changed by your ISP any time. This address is not the
routing gateway's address for LAN IPv6 hosts.
A unique local address (ULA) is a unique IPv6 address for use in private networks but not
routable in the global IPv6 Internet.
Select this to have the Device automatically generate a globally unique address for the LAN
IPv6 address. The address format is like fdxx:xxxx:xxxx:xxxx::/64.
If you select static IPv6 address, enter the IPv6 address prefix that the Device uses for the
LAN IPv6 address.
If you select static IPv6 address, enter the IPv6 prefix length that the Device uses to
generate the LAN IPv6 address.
An IPv6 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.
Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the presence
of MLD hosts who wish to receive multicast packets and the IP addresses of multicast
groups the hosts want to join on its network. Select Enable MLD Snooping 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 Standard Mode to have the Device forward IPv6 multicast packets to a port that
joins the IPv6 multicast group and broadcast unknown IPv6 multicast packets from the WAN
to all LAN ports.
Select Blocking Mode to have the Device block all unknown IPv6 multicast packets from
the WAN.
Select how you want to obtain an IPv6 address:
• stateless + DNS send by RADVD: The Device uses IPv6 stateless autoconfiguration.
RADVD (Router Advertisement Daemon) is enabled to have the Device send IPv6 prefix
information in router advertisements periodically and in response to router solicitations.
DHCPv6 server is disabled. (See
• stateless + DNS send by DHCPv6: The Device uses IPv6 stateless autoconfiguration.
The DNS is provided by a DHCPv6 server.
• stateful + DHCPv6 server: The Device uses IPv6 stateful autoconfiguration. The
DHCPv6 server is enabled to have the Device act as a DHCPv6 server and pass IPv6
addresses, DNS server and domain name information to DHCPv6 clients.
• stateful + DHCPv6 relay: The Device uses IPv6 stateful autoconfiguration. DHCPv6
Relay is enabled to have the Device relay client DHCPv6 requests.
This shows the status of the DHCPv6.
Select From ISP if your ISP dynamically assigns IPv6 DNS server information.
Select User-Defined if you have the IPv6 address of a DNS server. Enter the DNS server
IPv6 addresses the Device passes to the DHCP clients.
Select None if you do not want to configure IPv6 DNS servers.
If DHCPv6 is enabled, specify the first IPv6 address in the pool of addresses that can be
assigned to DHCPv6 clients.
