Configurations between IPv6 and IPv4 on Huawei MA5800 OLT and MA5600T OLT vary in the ACL, security feature, and IPTV multicast service.
Configuration Difference in Each Scenario
Table 1 lists the configuration differences between IPv6 and IPv4 on the OLT in each scenario. For details about the commands, see the later sections.
| Service | Scheme | Configuration Difference Between IPv6 and IPv4 |
| HSI | IPv4/IPv6 DS+NAT+PPPoE | The ACL and anti-IP spoofing configurations are different for the two services. |
| IPv4/IPv6 DS+NAT+IPoE | The ACL, anti-IP spoofing, and DHCP option configurations are different for the two services. | |
| DS-Lite+PPPoE | The ACL and anti-IP spoofing configurations are different for the two services. | |
| IPTV | IPv4/IPv6 DS+IPoE | The ACL, anti-IP spoofing, DHCP option, and multicast IGMP protocol configurations are different for the two services. |
ACL
ACL configurations on the OLT are different for IPv6 and IPv4 on networks running both IPv4 and IPv6 services, regardless of networking scenarios and service implementation schemes.
When configuring basic and advanced IPv6 ACLs, ensure that the keyword “ipv6” is included in the configuration command.
For details, see Table 2.
| IPv4 | IPv6 | IPv6 ACL Supported or Not |
| acl | acl ipv6 | Supported |
| packet-filter { inbound | outbound } | packet-filter { inbound | outbound } ipv6 | Supported |
| rule | rule | Supported
Note:After IPv6 is introduced, the protocol parameter in the rule command is extended to support the IPv6 protocols. |
Security Feature
Anti-IP spoofing configurations for IPv6 and IPv4 are different on networks running both IPv4 and IPv6 services, regardless of networking scenarios and service implementation schemes.
If the IPoE and DHCP protocols are used, DHCP option configurations for IPv6 and IPv4 are also different. For details, see Table 3.
| IPv4 | IPv6 | IPv6 Security Supported or Not |
| DHCP Option | ||
| raio-mode mode dhcp-option82 | raio-mode mode dhcpv6-option | Supported |
| dhcp option82 | dhcpv6 option | Supported |

| security anti-ipspoofing | security anti-ipv6spoofing | Supported |
| display security bind ip | display security bind ipv6 | Supported |
Key Differences
- The IP addresses in anti-IP spoofing configurations are different for the two services.
- In IPv4 configuration, the DHCP option is DHCPv4 Option 82.
- In IPv6 configuration, the DHCP option is DHCPv6 Option 18/37.
DHCP Option and RAIO Function
The DHCP option function works together with the RAIO function, enabling Huawei OLT to include physical user information, such as RID and CID, including subrack, slot, and port information.
This allows the BRAS or DHCP server to perform user authentication and tracking.
- When DHCPv4 is used, the OLT includes RID and CID in the Option 82 field.
- When DHCPv6 is used, the OLT includes:
- RID in the Option 37 field
- CID in 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 IPTV multicast services are different between IPv4 and IPv6 on the OLT.
- IPv4 uses the IGMP protocol.
- IPv6 uses the MLD protocol, which is the IPv6 equivalent of IGMP.
The IPv4 multicast service can share VLANs with the IPv6 multicast service. Therefore, IPv6 multicast services can be deployed within existing IPv4 M-VLANs by simply adding IPv6 multicast programs and related profiles.
The following configured parameters can remain unchanged:
- Bound right profiles
- M-VLANs
For details about the differences in IGMP commands between the two services, see Table 4.
