Table 27 IPv6 LAN Auto Configuration
LABEL DESCRIPTION
Interface Address To use a static IPv6 address, enter the IPv6 address prefix and prefix length that
the Router uses for the LAN IPv6 address.
The 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.
Enable DHCPv6
Server
Select this to have the Router act as a DHCPv6 server and pass IPv6 addresses,
DNS server and domain name information to DHCPv6 clients.
Stateless Select this to have the Router use IPv6 stateless autoconfiguration.
Stateful Select this to have the Router use IPv6 stateful autoconfiguration.
Start interface ID: specify the first IPv6 address in the pool of addresses that
can be assigned to DHCPv6 clients.
End interface ID: specify the last IPv6 address in the pool of addresses that can
be assigned to DHCPv6 clients.
Leased Time (hour): Specify for how many hours to assign an IPv6 address to a
DHCPv6 client before making it available for reassignment to other systems.

Enable RADVD Select this to have the Router 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.
Randomly
Generate
Select this to automatically create a LAN IPv6 address prefix.
