access). The OLT and ONU work with upper-layer devices to support Huawei DS+NAT
+PPPoE/DS+NAT+IPoE HSI IPv6 solutions.
l
For voice services: The ONU with a built-in voice module can directly provide VoIP
services for users. The ONU processes VoIP services using the IPv4 protocol instead of
the IPv6 protocol.
l
For Internet access services: Users connect to the ONU through category-5 cables (LAN
access) or the modem and twisted pairs (xDSL access). The PC and BRAS support the
IPv4/IPv6 DS and can be connected in the PPPoE or IPoE mode. The OLT and ONU
implement Layer 2 forwarding, irrespective of whether the access service is IPv4 or IPv6.
Service configurations for IPv4 and IPv6 are the same. Only the ACL, anti-IP spoofing,
and DHCP option configurations for IPv4 and IPv6 are different.

19.3.2 Data Planning
This section describes the security, device management data, QoS, Internet service data, and
voice service data planning.
Security Planning
Security planning includes system security, user security, and service security, ensuring that user
services are provided properly from different dimensions.
In the FTTB/C (no HGW) networking scenario, the data for IPv6 and IPv4 security planning
differs only in anti-IP spoofing and DHCP option.
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.
