DESCRIPTION
Select DHCP if you want to obtain an IPv6 address from a DHCPv6 server.
The IP address assigned by a DHCPv6 server has priority over the IP address
automatically generated by the Device using the IPv6 prefix from an RA.
Select SLAAC (Stateless address autoconfiguration) to have the Device use the prefix
to automatically generate a unique IP address that does not need to be maintained by
a DHCP server.
Selelct Auto to have the Device indicate to hosts for IPv6 address generation
depending on the M/O (Managed/Other) flag values in the router advertisements
sending to hosts.
• If M flag is 1, the Device will indicate to hosts to obtain network settings (such as
WAN IP, LAN prefix and DNS settings) through DHCPv6.
• If M flag is 0, the Device will check O flag.
• If O flag is 1, the Device will indicate to hosts to obtain DNS information and LAN
prefix through DHCPv6.
• If O flag is 0, the Device will not get information through DHCPv6.
Select Enable to use DHCP PD (Prefix Delegation) to allow the Device to pass the
IPv6 prefix information to its LAN hosts. The hosts can then use the prefix to generate
their IPv6 addresses.
Select Manual to manually enter a WAN Identifier as the interface ID to identify the
WAN interface. The WAN Identifier is appended to the IPv6 address prefix to create
the routable global IPv6 address. Select EUI64 to use the EUI-64 format to generate
an interface ID from the MAC address of the WAN interface.
If you selected Manual, enter the WAN Identifier in this field. The WAN identifier
should be unique and 64 bits in hexadecimal form. Every 16 bit block should be
separated by a colon as in XXXX:XXXX:XXXX:XXXX where X is a hexadecimal
character. Blocks of zeros can be represented with double colons as in
XXXX:XXXX::XXXX.
Select Always On when you want your connection up all the time. The Device will try
to bring up the connection automatically if it is disconnected.
Select Instant On when you don't want the connection up all the time and specify an
idle time-out in the Max Idle Timeout field.
Click this to display the Advanced WAN Setup screen and edit more details of your
WAN setup. Click this button again to display less fields in this screen.
RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. Use this field to control how much routing information the Device
sends and receives on the subnet.
Select the RIP direction from None, Both, In Only and Out Only.
This field is not configurable if you select None in the RIP Direction field.
Select the RIP version from RIP-1, RIP2-B/RIP2-M.
Multicast packets are sent to a group of computers on the LAN and are an alternative
to unicast packets (packets sent to one computer) and broadcast packets (packets
sent to every computer).
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a multicast group. The Device supports IGMP-v1/IGMP-v2/IGMP-
v3. Select None to disable it.
