Re: [IPsec] FW: I-D Action:draft-nir-ipsecme-childless-00.txt

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
