All of which taken together indicates the Sec. 3.6 needs to be rewritten. It'll be hard enough to get interoperability with all these options, but certainly if much remains undocumented. We might even need to resort to defining what the mythical minimal implementation is allowed to do. Thanks,

I would repeat my comment from April: http://www.ietf.org/mail-archive/web/ipsec/current/msg04245.html If we continue to allow CP in INFORMATIONAL exchange (and IMHO we should), it should be allowed in CREATE_CHILD_SA, too (with exactly same semantics). Best regards, Pasi From:

I disagree. Payloads in a particular CREATE_CHILD_SA exchange should be specifically related to the SA being created. The IKE_AUTH exchange is different, because it is used to set up everything we need to get an IPsec SA going. We do not use the CREATE_CHILD_SA to delete old SAs, to query

Tero, in short: 1) I still prefer to echo back TS payloads as I described. I realize that the TS payloads are the only opportunity that IKEv2 has to reproduce the effect of IKEv1's NAT-OA payloads. But using the traffic selectors in this way -- and only if the responder ends up agreeing to
