XAUTH?



Hi,

Config Mode states:

   "A "Configuration Transaction" is defined as two configuration
   exchanges, the first being either a Set or a Request and the second
   being either an Acknowledge or a Reply, respectively.

...
   Transactions are completed once the Reply or Acknowledge code is
   received."

To me this means that the message ID is unique for the transaction, either a
Set-Ack or Request-Reply pair.

However XAUTH states:
All ISAKMP-Config messages in an extended authentication
   transaction MUST contain the same ISAKMP-Config message ID.

And gives examples where a Request-Reply is followed by a Set-Ack and is
referred to as a "transaction".

Are the message ID's unique for the Request-Reply and Set-Ack in XAUTH or
are they the same?
