I am not sure that the absence/presence of NAS-IP-Address/NAS-IPv6-Address necessarily provides information about the nature of the traffic within RADIUS accounting. For example, it is quite possible that both attributes will be present. Is there a reason why we can't just define accounting attributes to provide the information you're looking for? ======================================================= > CC: dromasca@avaya.com; iesg@ietf.org; Bernard_Aboba@hotmail.com; softwire-chairs@tools.ietf.org; draft-ietf-softwire-hs-framework-l2tpv2@tools.ietf.org > From: bruno.stevant@telecom-bretagne.eu > To: Pasi.Eronen@nokia.com > Subject: Re: DISCUSS: draft-ietf-softwire-hs-framework-l2tpv2 > Date: Fri, 27 Mar 2009 09:39:31 +0100 > > Hi all, > > Just an update on one item: > > [snip] > > > >> * RFC 2866, by referencing draft-stevant-softwire-accounting, which > >> redefines the format of the NAS-IP-Address attribute (which only > >> supports IPv4 addresses; NAS-IPv6-Address is used to contain IPv6 > >> addresses). > > > > It looks like draft-stevant-... indeed has text that isn't correct > > (but also looks easy to fix).
