Title

  Test IKEv2.EN.I.1.1.6.5: Sending Multiple Transforms for CHILD_SA
  Part C: Multiple Extended Sequecnce Numbers (ADVANCED)


Purpose

  To verify an IKEv2 device properly transmits IKE_AUTH request with multiple transforms
  for CHILD_SA.


References

  * [RFC 4306] - Sections 2.7 and 3.3


Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the following configuration.
IKE_AUTH exchanges Algorithms
Encryption Integrity ESN
Part C ENCR_3DES AUTH_HMAC_SHA1_96 NoESN
ESN
  * Pre-Sequence and Cleanup Sequence
      IKEv2 on the NUT is disabled after each part.

    |                    |
    |------------------->| IKE_SA_INIT request (HDR, SAi1, KEi, Ni)

       9. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request including a SA payload
          as described above to the TN1.
      10. Observe the messages transmitted on Link A.
      11. NUT transmits an IKE_AUTH request including a SA payload as described above to the
          TN1.
      12. Observe the messages transmitted on Link A.


Observable Result

  Part C
    Step 10: 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 12: Judgment #2
      The NUT transmits an IKE_AUTH request including "ENCR_3DES",
      "AUTH_HMAC_SHA1_96", "No Extended Sequence Numbers" and "Extended Sequence
      Number" as proposed algorithms.


Possible Problems

  * None.
