EAP requestor for Initiator

[Tom Hu <tomhu@cisco.com>]

Hi all,

In the ikev2 draft, explicitely describes EAP request initiated from
Responder. Is it legit to have EAP request initiated from Initiator?
Please see the below exchange. Is this against IKEv2 protocol?

Note: when I said EAP requestor, it means that the node sends the first
EAP packet.


  Initiator                          Responder
 -----------                        -----------
  HDR, SAi1, KEi, Ni         -->
                              <--    HDR, SAr1, KEr, Nr, [CERTREQ]

  HDR, SK {IDi, [CERTREQ,] [IDr,]
           SAi2, TSi, TSr}   -->
                              <--    HDR, SK {IDr, [CERT,] AUTH}
  HDR, SK {EAP, [AUTH]}      -->
                              <--    HDR, SK {EAP, [AUTH]}

  HDR, SK {EAP, [AUTH] }     -->
                              <--    HDR, SK {[AUTH], SAr2, TSi, TSr }

Thanks,
