Configuration Difference Between IPv6 and IPv4

The main configuration difference between the IPv6 and IPv4 services lies in the

configurations on the OLT, MDU, and ONT.

Configuration Differences Between IPv6 and IPv4 on the Huawei OLT Configurations between IPv6 and IPv4 on the OLT vary in the ACL, security feature, and

IPTV multicast service.

Configuration Difference in Each Scenario

Table 1lists the configuration difference between IPv6 and IPv4 on the OLT in each

scenario. For details about the commands, see the later section.

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. For details, see Table 2

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. For details, see Table 3.

1 The IP addresses in anti-IP spoofing configurations are different for the two services.

2 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 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. For details about the difference of the IGMP commands between

the two services, see Table 4.

Configuration Difference Between IPv6 and IPv4 on the ONTFor the bridging ONT, configurations for IPv6 and IPv4 are the same. For the gateway

ONT, the HSI service configurations for IPv6 and IPv4 are different.

Configuring the IPv6 WAN Port on the Gateway ONT11

For IPv6 IPTV multicast service, no extra configuration is required. For the IPv6 HSI

service, the Internet WAN port on the gateway ONT must be configured (only Internet

WAN port supports IPv6). If the gateway ONT uses the IPv6/IPv4 DS scheme, select

IPv4/IPv6 for Protocol Type. If the gateway ONT uses the DS-Lite scheme, select IPv6

for Protocol Type. For details, see Figure 1.

Figure 1 Configuring the IPv6 WAN port

Configuring the IPv6 Address of the LAN Side on the Gateway ONTThe gateway ONT can be configured to allocate IPv6 addresses to the terminals after

IPv6 is introduced. For details, see Figure 2.

Figure 2 Configuring the IPv6 address on the LAN side

Configuring the Static IPv6 Route on the Gateway ONTThe gateway ONT can be configured with the static IPv6 route after IPv6 is introduced.

For details, see Figure 3.
