Test IKEv2.EN.R.1.1.3.1: State Synchronization with ICMP messages Part A: (BASIC)
To verify that an IKEv2 device doesn't conclude that the other endpoint has faild by receiving ICMP Error messages.
* [RFC 4306] - Sections 2.1, 2.2 and 2.4
* 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 A: (BASIC) 1. TN1 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, TN1 transmits an IKE_AUTH request 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. 7. After reception of an Echo Reply from NUT, TR1 transmits ICMP Destination Unreachable Message to the NUT. 8. TN1 transmits an Echo Request with IPsec ESP using corresponding algorithms to NUT. 9. Observe the messages transmitted on Link A.
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 Echo Reply with IPsec ESP using corresponding algorithms. Step 9: Judgment #4 The NUT transmits an Echo Reply with IPsec ESP using corresponding algorithms.
* None.
