My understanding of CONNECTED notification goes like this;
HDR*, HASH(1), SA, Ni
[, KE ] [, IDci, IDcr ] -->
<-- HDR(commit)*, HASH(2), SA, Nr
[, KE ] [, IDci, IDcr ]
HDR*, HASH(3) -->
Commit bit is used to signal the use of CONNECTED notification by the
sending entity, Responder in this case. Initiator waits for CONNECTED
notification, IPsec SAs are established after the receipt and
processing of this notification. IMHO, only the AM/QM responders get
the advantage of this functionality, i.e. not much use for initiators
to set the commit bit.
