Hi Ian, indeed. Would however prefer to remove the modal verb however (which leads to a few changes):
Lightweight 4over6 is a solution designed specifically for complete independence between IPv6 subnet prefix and IPv4 address with or without IPv4 address sharing. This is accomplished by maintaining state for each softwire (per-subscriber state) in the central lwAFTR and a hub-and-spoke forwarding architecture. [I-D.ietf-softwire-map] also offers these capabilities or, alternatively, allows for the reduction of the amount of centralised state by means of rules expressing an algorithmic address mapping relationship between the IPv6 subnet prefix and IPv4 address. This relationship also allows the option of direct, meshed connectivity between users. Cheers, Wojciech.
