31.3 IPv6 multicast forwarding function
Forwarding of multicast packets is performed in hardware and software based on IPv6 multicast forwarding entries. Forwarding information for forwarded IPv6 multicast packets is registered in hardware IPv6 multicast forwarding entries upon forwarding. Registered IPv6 packets are forwarded by hardware, and unregistered IPv6 packets are forwarded based on IPv6 multicast forwarding entries generated by software IPv6 multicast routing information. The IPv6 multicast forwarding functionality is the same as the IPv4 multicast forwarding functionality except that there are restrictions on addresses subject to forwarding in the IPv6 multicast forwarding functionality.
