Pre-Sequence
In order to start the negotiation of IKE,
NUT transmits Echo Request to TN(HOST-2).
This test check is following.

Judgement (Check *1)
1. Send the first message from TN
In the first message (1), the initiator generates a proposal it
considers adequate to protect traffic for the given situation. The
Security Association, Proposal, and Transform payloads are included
in the Security Association payload (for notation purposes).
Keying material used to arrive at a common shared secret and random
information which is used to guarantee liveness and protect against
replay attacks are also transmitted. Additionally, the initiator
transmits identification information.
2. Receive the second message from NUT
In the second message (2), the responder indicates the protection
suite it has accepted with the Security Association, Proposal, and
Transform payloads.
Keying material used to arrive at a common shared secret and random
information which is used to guarantee liveness and protect against
replay attacks is also transmitted.Additionally, the responder
transmits identification information and the results of the agreed
upon authentication function(hash function).
The second message which has correct position of payload must be received
(The SA payload MUST precede all other payloads).
And must conform to above Configuration.

(omit)
The SA payload MUST precede all other payloads in a phase 1 exchange.
Except where otherwise noted, there are no requirements for ISAKMP
payloads in any message to be in any particular order.
