Title

  Test IKEv2.EN.R.1.1.4.1: Receipt of a higher minor version number
  Part A: (BASIC)


Purpose

  To verify an IKEv2 device aceepts a request with a higher minor version number and respond
  to the request.


References

  * [RFC 4306] - Sections 2.5


Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the Common Configuration.
  * Pre-Sequence and Cleanup Sequence
      IKEv2 on the NUT is disabled after each part.


Procedure

   NUT                  TN1

Packet #1 See below

* Packet #1: IKE_SA_INIT request
IPv6 Header Same as the Common Packet #1
UDP Header Same as the Common Packet #1
IKEv2 Header Other fields are same as the Common Packet #1
Major Version 2
Minor Version 1
SA Payload Same as the Common Packet #1
KE Payload Same as the Common Packet #1
Ni, Nr Payload Same as the Common Packet #1
  Part A: (BASIC)
       1. TN1 starts to negotiate with NUT by sending IKE_SA_INIT request with a higher minor
          version number.
       2. Observe the messages transmitted on Link A.


Observable Result

  Part A
    Step 2: Judgment #1
      The NUT transmits an IKE_SA_INIT response including "ENCR_3DES",
      "PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96" and "D-H group 2" as accepted
      algorithms.


Possible Problems

  * None.
