you can do either. embedding a complete IPv4 address and PSID does require a lot of IPv6 space though. e.g. /56 - 32 - 6 = /18 1:1 mode is typically referred to a model where IPv4 and IPv6 addressing are independent. cheers, Ole _______________________________________________ Softwires mailing list Softwires@ietf.org https://www.ietf.org/mailman/listinfo/softwires
