– If the STB uses PPPoE, it establishes a PPPoE connection to the BRAS. The OLT, ONU,
and HGW only forward PPPoE service flows and do not process multicast services.
Therefore, this scheme is not recommended.
l Voice service: The voice service can be provided by the ONU with the build-in voice
module or the build-in IAD of the HGW. The VoIP service on ONU or HGW is still
implemented by IPv4.

19.4.2 Data Planning
This section describes the security, device management data, QoS, Internet service data, voice
service data, and IPTV service data planning.
Security Planning
Security planning includes system security, user security, and service security, ensuring user
services are provided properly from different dimensions.
In the FTTB+HGW networking scenario, only anti-IP spoofing and DHCP option of IPv6 and
IPv4 services are different.
Anti-IP spoofing: This function needs to be configured separately for IPv6 services.
The anti-IP spoofing function can be enabled or disabled at three levels. This function takes
effect only when it is enabled at all the three levels.
1. Global level: Run the security anti-ipv6spoofing enable command in global config mode.
2. VLAN level: Run the security anti-ipv6spoofing enable command in VLAN service
profile mode.
3. Service port level: Run the security anti-ipv6spoofing service-port serviceport-id
enable command.
DHCP option: The DHCP option for IPv4 is DHCPv4 option 82 and for IPv6 is DHCPv6 option
18/37.
