Internet service: The PC and BRAS support the IPv4/IPv6 dual-stack and are connected
using the PPPoE or IPoE dial-up. The OLT and ONT have the same forwarding and
configuration methods for both IPv4 and IPv6 user services. The only difference is that
commands for configuring the ACL and security (DHCP option and anti-IP spoofing)
features are different.
–
For DS+NAT+PPPoE and DS+NAT+IPoE solutions, both the ONT and BRAS support
IPv4/IPv6 dual-stack and are connected using PPPoE or IPoE. The ONT must enable
the IPv4 and IPv6 simultaneously at the WAN port. The OLT performs Layer 2
forwarding for both IPv4 and IPv6 user services, which are configured almost in the
same way. The only difference is that commands for configuring the ACL and security
features (DHCP option and anti-IP spoofing) are different.
–
For DS-Lite+PPPoE, the BRAS must support IPv4/IPv6 dual-stack while the ONT
supports the DS-Lite. The ONT and BRAS are connected using PPPoE. The HGW
encapsulates IPv4 service packets into the 4in6 tunnel, and transmits them to the CGN
for decapsulation. The ONT must enable DS-Lite at the WAN port. The OLT performs
Layer 2 forwarding for both IPv4 and IPv6 user services, which are configured almost
in the same way. The only difference is that commands for configuring DHCP option
and anti-IP spoofing are different.
l
IPTV service: The STB supports IPv4/IPv6 dual-stack and carries IPTV services using
either IPv4 or IPv6.
–
When the STB uses IPoE and the OLT functions as the multicast duplicate point, the
process for configuring IPv6 and IPv4 multicast services is the same, but commands
are different. The OLT and ONU perform bridge forwarding for both IPv4 and IPv6
user services, which can be configured almost in the same way.
–
When the STB uses PPPoE, it directly connects to the BRAS by PPPoE. The OLT and
ONT only forward PPPoE services instead of processing multicast services. This
solution is not recommended.
