Parameter Description
IP Acquisition Mode Indicates the IP acquisition mode. It can be set to DHCPv6, Automatic, Static, or None.
If this parameter is set to Automatic, you need to make the prefix mask 64-bit long.
The prefix mask length of the IPv6 address is similar to the subnet mask of the IPv4 address.
If this parameter is set to Static, you need to enter the IP address, primary DNS server, and secondary
DNS server.
The ONT address mode can be Numbered or Unnumbered. When the address mode is Numbered, the ONT
WAN port has its own IPv6 GUA address. When the address mode is Unnumbered, the ONT WAN port has an
LLA address but no GUA address, which is not good for network management and fault location. Therefore, the
Numbered mode is recommended.
When the Numbered mode is used, the setting of IP Acquisition Mode is as follows:
When M=1 is set for the RA packet on the BRAS, IP addresses are obtained in DHCPv6
mode on the WAN side. Then, IP acquisition mode can be set to DHCPv6 or Automatic.
Automatic is recommended.
When M=0 is set for the RA packet on the BRAS, IP addresses are obtained in ND (stateless
address allocation) mode on the WAN side. Then, IP acquisition mode can be set to
Automatic.
When the Unnumbered mode is used, IP acquisition mode is set to None.
Multicast VLAN ID The multicast VLAN ID ranges from 1 to 4094.
The multicast VLAN ID must be the same as the multicast VLAN ID on the OLT.
DSLite work mode Indicates that the IPv4 packet is encapsulated into the IPv6 packet and transmitted through IPv6 tunnel. This
work mode is only enabled for the DS-Lite solution.
Off: Indicates the DSLite work mode is disabled.
Auto: Indicates that the IP address and domain name of the peer device at the tunnel are automatically
obtained using RA or DHCP protocol.
Static: Indicates that the IP address and domain name information of the peer device at the tunnel are
manually entered. When this mode is used, you need to enter the AFTR domain name which must be
consistent with that on the BRAS.
AFTR name Indicates the IP address or domain name of the peer device at the tunnel. AFTR is short for address family
transition router.
WAN Configuration - bridge
1. In the navigation tree on the left, choose Advanced Configuration > WAN Configuration. In the pane on the right, click New. In
the dialog box that is displayed, set Mode to Bridge WAN, as shown in Figure 3.
