Folks, I got a brief look at 501bis on some parts, specifically what comes to Mobile Node (3GPP) parts. It would be good to make a check against TS29.061 on the actually supported & required RFC.. or draft-ietf-v6ops-3gpp-eps-08, which takes quite a detailed but condensed peek into 3GPP IPv6 aspects. Quick comments on DHCPv6. The DHCPv6 support for Mobile Node is only for IPv6 parameter configuration via stateless DHCPv6 RFC3736, stateful address configuration (for the Mobile Node) is not supported at all. I also have concerns on IKE and IPsec 'mandatory support' text for Mobile Nodes as that is not the case in today's 3GPP standards as far as I remember. Furthermore, listing both rfc3041 and rfc4941 is not needed as the latter obsoletes the former. On the references part I do not understand why also 3GPP2 is included. Earlier in the document and in the definition part it was made quite clear "Mobile Node" refers only to 3GPP. These are just comments that could be taken into account in some future revision of 501bis. I can actually help crafting the text ;) - Jouni -- Jouni Korhonen Nokia Siemens Networks
