Since IPv4-translatable address is a /128 inside /64, when the configuration parameters are given (see above), the routing can guide the translated packets to the translation API. xing > Thanks, > washam > _______________________________________________ > Softwires mailing list > Softwires@ietf.org > https://www.ietf.org/mailman/listinfo/softwires > >
