That's fine, but personally I think that it's just good protocol design to reduce the coupling between layers to the bare minimum required. RFC 3748 has to its credit the fact that it made explicit the dependency of EAP upon the delivery characteristics of PPP that were implicit in RFC 2284; unfortunately, it leaves that dependency in place even though a fix is easy enough. > > Yoshihiro Ohba _______________________________________________ Pana mailing list [email protected] https://www1.ietf.org/mailman/listinfo/pana
