Title

  Test IKEv2.EN.R.1.1.8.3: INVALID_SELECTORS
  Part A (BASIC)


Purpose

  To verify an IKEv2 device properly handles an ESP or AH packet whose selectors do not
  match those of the CHILD_SA.


References

  * [RFC 4306] - Sections 3.10.1
  * [RFC 4307] - Sections 7.8


Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the Common Configuration except
      Traffic Selector. Traffic Selector should be configured as following.
Traffic Selector

Outbound NUT TCP ANY TN1 TCP ANY

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

  Part A (BASIC)
       1. TN starts to negotiate with NUT by sending IKE_SA_INIT request.
       2. Observe the messages transmitted on Link A.
       3. After reception of IKE_SA_INIT response from the NUT, TN transmits an IKE_AUTH
          request as the above table to the NUT.
       4. Observe the messages transmitted on Link A.
       5. After reception of IKE_AUTH response from the NUT, TN1 transmits an Echo Request
          with IPsec ESP using corresponding algorithms to NUT.
       6. 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.
  
    Step 4: Judgment #2
      The NUT transmits an IKE_AUTH response including "ENCR_3DES",
      "AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as accepted algorithms.
    Step 6: Judgment #3
      The NUT transmits an INFORMATIONAL request with a Notify of type
      INVALID_SELECTORS.


Possible Problems

  * None.
