Title

  Test IKEv2.EN.R.1.1.4.5: Invalid Order Payloads
  Part A: (BASIC)


Purpose


  To verify an IKEv2 device properly handles IKE message with invalid order payloads.


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
(End-Node)           (End-Node)
    |                    |
    |<-------------------| IKE_SA_INIT request (HDR, SAi1, Ni, KEi)
    |                    | (Packet #1)
    |---------X          | IKE_SA_INIT response (HDR, SAr1, KEr, Nr)

Packet #1 See Common Packet #1
KEi payload and Ni payload replace each other.
  Part A (BASIC)
     1. TN 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 never 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.
