schemes. If the IPoE and DHCP protocols are used, DHCP option configurations for IPv6 and
IPv4 are also different. For details, see
.
l
The IP addresses in anti-IP spoofing configurations are different for the two services.
l
In the IPv4 configuration, DHCP option is DHCPv4 option 82. In the IPv6 configuration,
DHCP option is DHCPv6 option 18/37.
In the IPv6 configuration, the DHCP option function is used together with the RAIO
function, which enables the ONU to include physical information (including RID and CID)
of the user, such as the subrack/slot/port. In this way, the BRAS or DHCP server is able to
perform user authentication and tracing. When DHCPv4 is in use, the ONU includes RID
and CID to the option 82 field. When DHCPv6 is in use, the ONU includes the RID to the
option 37 field in the DHCPv6 packet and the CID to the option 18 field. The sub option
7 and sub option 9 functions of DHCPv4 option 82 are not supported by DHCPv6.

IPTV Multicast Service
The IGMP protocol configurations (used to implement the IPTV multicast service) for IPv6 and
IPv4 on the ONU are different. IPv4 uses the IGMP protocol while IPv6 uses the MLD protocol
(the IGMP protocol for IPv6). The IPv4 multicast service can share VLANs with the IPv6
multicast service; therefore, you can deploy the IPv6 multicast service in existing IPv4 MVLANs
only by adding IPv6 multicast programs in the IPv4 MVLANs and in right profiles. The
