Test IKEv2.EN.R.1.1.1.3: Use of CHILD_SA Part A (BASIC)
To verify an IKEv2 device properly handles CHILD_SA negotiated by the Initial Exchanges using Pre-shared key.
* [RFC 4306] - Sections 1.2
* 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 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 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.
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.
