Title

  Test IKEv2.EN.I.1.1.6.4: Sending Multiple Proposals for IKE_SA
  Part A: (ADVANCED)

Purpose

  To verify an IKEv2 device properly transmits IKE_AUTH request with multiple proposals
  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_SA_INIT exchanges Algorithms
	Proposal	Protocol ID	Encryption	PRF	Integrity	D-H Group
Part A	Proposal #1	IKE	ENCR_3DES	PRF_HMAC_SHA1	AUTH_HMAC_SHA1_96	Group2
	Proposal #2	IKE	ENCR_AES_CBC	PRF_AES128_CBC	AUTH_AES_XCBC_96	Group14

  * Pre-Sequence and Cleanup Sequence
      IKEv2 on the NUT is disabled after each part.

Procedure

   NUT                  TN1
(End-Node)           (End-Node)
    |                    |
    |------------------->| IKE_SA_INIT request (HDR, SAi1, KEi, Ni)
    |                    | (Judgement #1)
    |                    |
    V                    V

  Part A: (ADVANCED)
       1. TN1 starts to negotiate with NUT by sending IKE_SA_INIT request.
       2. Observe the messages transmitted on Link A.

Observable Result

  Part A
    Step 2: 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" in SA Proposal #1
      (ESP) and "ENCR_AES_CBC", "PRF_AES128_CBC", "AUTH_AES_XCBC_96" and
      "D-H group 14" in SA Proposal #2 (ESP) as proposed algorithms.

Possible Problems

  * None.
