I think we're talking about different things. what I think Fred was suggesting was that it should be possible to delegate prefixes using DHCPv6 PD (and addresses for that matter) over various types of tunnels. the prefixes/addresses delegated/assigned would then be entirely independent of the link-layer addressing (IPv4), and purely use the automatic tunnelling mechanism for transport. similar to BGP tunnelling. cheers, Ole _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
