Configuration Differences Between IPv6 and IPv4 on the OLT EA5801-GP08
Configurations between IPv6 and IPv4 on the OLT EA5801-GP08 vary in the ACL, security feature, and IPTV multicast service.
Configuration Difference in Each Scenario
Configuration difference between IPv6 and IPv4 on the OLT
| 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 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.
Commands for configuring IPv4 and IPv6 ACL on the OLT
| 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 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 OLT 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 M-VLANs only by adding IPv6 multicast programs in the IPv4 M-VLANs and in right profiles. The configured parameters such as the bound right profiles and M-VLANs can remain unchanged. For details about the difference of the IGMP commands between the two services.
