METHOD AND APPARATUS FOR INTERNET PROTOCOL VERSION SIX (IPV6) ADDRESSING AND PACKET FILTERING IN BROADBAND NETWORKS

摘要

A method for Internet Protocol version six (IPv6) addressing and packet filtering in broadband networks, comprising sending a dynamic host configuration protocol (DHCP) message comprising an Identity Association for Prefix Delegation (IA_PD) Prefix option comprising a Internet Protocol version 6 (IPv6) prefix and a length of the IPv6 prefix to a device having a media access control (MAC) address, receiving from the device a packet comprising a source MAC address and a source IPv6 address, and dropping the packet when the MAC address is equal to the source MAC address and the leftmost bits of the source IPv6 address defined by the length are not equal to the IPv6 prefix.
