Sending RAs unicast is already allowed by RFC 4861, so this is just an operational practice.

It simply clarified what has always been a fundamental premise of this operational practice: if you want to give each host its own prefix, you need to ensure that the RA with that prefix is only received by that host. 1) The protocol spec specified in this document requires the SLAAC > router to keep state of the "leased" prefixes -- what seems a major > change to SLAAC, which now would be kind of as stateful as DHCPv6. > This is a bizarre claim. The first-hop router must always have fully up-to-date state on all the prefixes it is sending RAs for, otherwise it cannot fulfill its fundamental purpose of forwarding traffic to those prefixes. The word "stateless" in SLAAC applies to addresses configured to the host, not how routers route traffic. 2) There are scenarios in which multiple nodes might receive the same > packet -- say a NIC let's the packet through because it is in > promiscuous mode -- wich could possibly lead to two nodes configuring > the same prefix. > Why do you say promiscuous mode is a problem? Even in promiscuous mode, network stacks already understand which packets are being send to the host network stack and which are not. For example, in the linux networking stack, well before the packet ever gets to the ICMPv6 protocol handlers that would process incoming RAs, ipv6_rcv does: if (skb->pkt_type == PACKET_OTHERHOST) { kfree_skb(skb); return NET_RX_DROP; } 3) What happens if the SLAAC router crashes and reboots, loosing state > of the "leased" prefixes? > You seem to be assuming that the router does not store the prefixes in stable storage. It's certainly the case that if you want this scheme to work across router crashes, then you need to ensure that the prefixes are stored somewhere. That sort of seems self-evident, but we could add it to the text. 4) How are prefixes selected? And, what's the minimum size of the pool > of prefixes for the selection algorithm not to break due two "prefix > collisions"? Does the selection algorithm have any specific properties? > I see no reason why this should be in scope for this document.
