missing ACK message

[vamsi <vamsi@xxxxxxxxxxxxx>]

Hi,

The following is the  general  Xauth transaction

IPSec Host                                              Edge Device

   --------------                                    -----------------

                                       <-- REQUEST

   REPLY -->

                                                    <-- SET

   ACK -->

Xauth draft of section 5  says  :

  " The Extended Authentication transaction is terminated either when

   the edge device starts a SET/ACK exchange which includes an

   XAUTH_STATUS attribute or when the remote device sends a

   XAUTH_STATUS attribute in a REPLY message.  Please note that a

   remote device can not set XAUTH_STATUS to anything but FAIL."

1)   Xauth  transaction  is terminated  when    the edge device starts a SET/ACK  exchange  ,is that termination  once after starting  or the completion of SET/ACK exchange?

2)Should edge device  wait for 'ACK' message  from the IpsecHost?

3)What happens if  by any chance that edge device  will not recive the 'Ack' message from the remote device(Ipsec Host)? 

bye
