Test IKEv2.EN.R.1.1.6.5: Receiving Multiple Transforms for CHILD_SA Part B: Multiple Integrity Algorithms (BASIC)
To verify an IKEv2 device properly handles IKE_AUTH request with multiple transforms.
* [RFC 4306] - Sections 2.7, 3.4 and 3.10.1 * [RFC 4718] - Sections 2.1 and 2.2
* 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: Multiple Integrity Algorithms (BASIC) 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 including a SA payload as described above 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 transmits an IKE_AUTH response including "ENCR_3DES", "AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as accepted algorithms.
* None.
