Test IKEv2.EN.R.1.2.8.1: AUTHENTICATION_FAILED Part B Invalid Auth method (ADVANCED)
To verify an IKEv2 device properly handles AUTHENTICATION_FAILED message.
* [RFC 4306] - Sections 3.10.1
* 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.

Part B Invalid Auth method (ADVANCED) 5. TN1 starts to negotiate with NUT by sending IKE_SA_INIT request. 6. Observe the messages transmitted on Link A. 7. After reception of IKE_SA_INIT response from the NUT, TN1 transmits an IKE_AUTH request which has an invalid Auth Method in AUTH payload to the NUT. 8. Observe the messages transmitted on Link A.
Part B Step 6: 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 8: Judgment #2 The NUT does not transmit an IKE_AUTH response or transmits an IKE_AUTH response with Notify payload of type AUTHENTICATION_FAILED without encryption to the TN1.
* None.
