The FTTH IPv6 solution is part of the Huawei fixed broadband solution for IPv6, supporting
the access of the IPv6 high speed Internet (HSI) service and IPTV service.
The Huawei FBB solution for IPv6 includes the following scenarios based on service access
modes. Since "HSI scenario: IPv4/IPv6 DS+PPPoE+L2TP" and "HSI scenario: IPv4/IPv6 DS
+NAT+PPPoE" in this solution are the same as those in Huawei FTTx solution, they are not
elaborated in this document.
- HSI scenario: IPv4/IPv6 DS+NAT+PPPoE
- HSI scenario: IPv4/IPv6 DS+NAT+IPoE
- HSI scenario: IPv4/IPv6 DS+PPPoE+L2TP
- HSI scenario: DS-Lite+PPPoE
- IPTV scenario: IPv4/IPv6 DS+IPoE
- IPTV scenario: IPv4/IPv6 DS+PPPoE
The access network devices still use IPv4, instead of IPv6, to implement voice services.
Configuration Difference Between IPv6 and IPv4
The main configuration difference between the IPv6 and IPv4 services lies in the
configurations on Huawei OLT, MDU, and ONT.
Configuration Differences Between IPv6 and IPv4 on the OLT
Configurations between IPv6 and IPv4 on the OLT vary in the ACL, security feature, and
IPTV multicast service.
ACL
ACL configurations on the OLT are different for IPv6 and IPv4 on the network which runs
both IPv4 and IPv6 services, irrespective of the networking scenarios and service
implementation schemes. When configuring basic and advanced IPv6 ACLs, ensure that the
keyword "ipv6" is included in the configuration command.
Security Feature
Anti-IP spoofing configurations for IPv6 and IPv4 are different on the network which runs
both IPv4 and IPv6 services, irrespective of the networking scenarios and service
implementation schemes. If the IPoE and DHCP protocols are used, DHCP option
configurations for IPv6 and IPv4 are also different.
The IP addresses in anti-IP spoofing configurations are different for the two services.
In the IPv4 configuration, DHCP option is DHCPv4 option 82. In the IPv6
configuration, DHCP option is DHCPv6 option 18/37.
The DHCP option function is used together with the RAIO function, which enables the
Huawei MA5800 MA5600T 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 OLT includes RID and CID to
the option 82 field. When DHCPv6 is in use, the OLT 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 OLT 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 configured parameters such as the bound right profiles and MVLANs can remain
unchanged.
