[Ipsec] Number of Proposals in IKE_SA_INIT exchange for IKE_SA andfirst CHILD_SA ??

[wadood <abdul.wadood@gmail.com>]

hi,

How may proposals Initiator will send in the first exchange i.e.,
IKE_SA_INIT. If Initiator wants to make two SAs i.e., IKE_SA and first
CHILD_SA(piggybacked with IKE_SA) having same cryptographic suite.

Or we can say 
A  single proposal for IKE_SA is sufficed for first CHILD_SA. If
CHILD_SA uses the same cryptographic suite as of IKE_SA.

Any comments/answers will be highly appreciated.
