=head1 Title

  Test IKEv2.EN.I.1.1.9.1: Sending IDi Payload
  Part D: ID_KEY_ID (BASIC)

=head1 Purpose

  To verify an IKEv2 device transmits IDi payload properly.

=head1 References

  * [RFC 4306] - Sections 3.5

=head1 Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the following configuration.

  Part D: ID_KEY_ID (BASIC)
      13. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request.
      14. Observe the messages transmitted on Link A.
      15. After reception of IKE_SA_INIT request from the NUT, TN1 responds with an
          IKE_SA_INIT response to the NUT.
      16. Observe the messages transmitted on Link A.

=head1 Observable Result

  Part D
    Step 14: Judgment #1
      The NUT transmits an IKE_SA_INIT request including "ENCR_3DES",
      "PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96" and "D-H group 2" as proposed
      algorithms.
  
    Step 16: Judgment #2
      The NUT transmits an IKE_AUTH request including an ID payload which contains the value
      specified as above table.

=head1 Possible Problems

  * None.
