address
automatically
Select this option to have the GPON Device use the IPv6 prefix from the connected
router’s Router Advertisement (RA) to generate an IPv6 address.
Dhcpv6 Address
Assignment
Select this check box 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 GPON Device using the IPv6 prefix from an RA.
Dhcp6c Prefix
Delegation
(IAPD)
Select this to use DHCP PD (Prefix Delegation) that enables the Device to pass the IPv6
prefix information to its LAN hosts. The hosts can then use the prefix to generate their
IPv6 addresses.
Use the following
Static IPv6 address
Select this option if you have a fixed IPv6 address assigned by your ISP.
WAN IPv6
Address/Prefix

Select Random to have the Device randomly configure a WAN Identifier, which is
shown in the WAN Interface Identifier field.
Select EUI-64 to use the EUI-64 format to generate an interface ID from the MAC
address of the WAN interface.
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.
WAN Interface
Identifier
If you selected Random, this field is automatically configured.
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.
