Verification Points
Determine if the Protocol is supported. If the Protocol-ID field
is invalid, the payload is discarded and the following actions
are taken:
(a) The event, INVALID PROTOCOL, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-PROTOCOL-ID message type MAY be sent
to the transmitting entity. This action is dictated by a
system security policy.

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).
2. Receive the second message from NUT
In the second message (2-B), the responder indicates either an ISAKMP
Notify Payload or an ISAKMP delete Payload.
The first message must not be accepted. And the second message(2-A)
must not be returned (* or INVALID-PROTOCOL-ID message(2-B) is returned).
*option : if you want to check the retruned Notify message.

5.5 Proposal Payload Processing
(omit)
When a Proposal payload is received, the receiving entity (initiator
or responder) MUST do the following:
1. Determine if the Protocol is supported. If the Protocol-ID field
is invalid, the payload is discarded and the following actions
are taken:
(a) The event, INVALID PROTOCOL, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-PROTOCOL-ID message type MAY be sent
to the transmitting entity. This action is dictated by a
system security policy.
2. Determine if the SPI is valid. If the SPI is invalid, the
payload is discarded and the following actions are taken:
(a) The event, INVALID SPI, MAY be logged in the appropriate
system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-SPI message type MAY be sent to the
transmitting entity. This action is dictated by a system
security policy.
3. Ensure the Proposals are presented according to the details given
in section 3.5 and 4.2. If the proposals are not formed
correctly, the following actions are taken:
(a) Possible events, BAD PROPOSAL SYNTAX, INVALID PROPOSAL, are
logged in the appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the BAD-PROPOSAL-SYNTAX or PAYLOAD-MALFORMED
message type MAY be sent to the transmitting entity. This
action is dictated by a system security policy.
4. Process the Proposal and Transform payloads as defined by the
Next Payload field. Examples of processing these payloads are
given in section 4.2.1.
