Hi Raj,
It sounds like you want a critical payload (RFC 4306, Sec. 2.5), probably a
payload with no data. In fact the draft could specify both options, the
current VID and such a payload, and leave it to the Initiator to decide
which behavior it prefers. Different scenarios might call for different
behaviors.
Thanks,
Yaron

Hi Yoav,
Mostly the Initiator will decide that it wants to bring UP only IKE SA
without child SA.
But currently there is no notify/VID from Initiator to Responder to indicate
that initiator wants to bring only IKE SA. Even if responder does not
supports "childless IKE_AUTH", it will process IKE_SA_INIT, involding CPU
intensive D-H calculations, and send IKE_SA_INIT response without "childless
VID" payload.
By introducing a notify/VID payload from Initiator that it wants to bring UP
only IKE SA without child SA wil ease the processing ar Responder side. If
responder does not support "childless IKE_AUTH", it can send INVALID_SYNTAX.
Then, Initiator will wait for "Child SA" info to be available to bring UP
both IKE and child SA, normally as mentioned in RFC 4306.
Thanks,
Raj
