from the draft: "A MAP node finds its Basic Mapping Rule by doing a longest match between the End-user IPv6 prefix and the Rule IPv6 prefix in the Mapping Rules table. The rule is then used for IPv4 prefix, address or shared address assignment." cheers, Ole _______________________________________________ Softwires mailing list Softwires@ietf.org https://www.ietf.org/mailman/listinfo/softwires
