Would you please explain it a bit more ? from MAP's perspective it doesn't matter if it is a /64 on the WAN or a /56 delegated prefix. any prefix can have EA bits. > 1) arbitrary IPv6 address (DS-lite) > Why it is arbitary ? Is it the source address of the tunnel endpoint ? in DS-lite the tunnel concentrator learns the tunnel endpoint address when the NAT bindings are created. so the CPE is free to pick whatever IPv6 address it has. this is different from Public 4over6 and LW46 where the address has to be configured on both ends. cheers, Ole _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
