The draft says: To avoid forwarding loops via other internal relays, the BR should employ outgoing and incoming IPv4 packets filters, filtering out all known relay addresses for internal 6rd BRs, ISATAP routers or 6to4 relays, including the well known anycast address space for 6to4. In my understanding, this will not filter any packet that should be forwarded.
