Test IKEv2.EN.R.1.2.9.1: Non zero RESERVED fields in CREATE_CHILD_SA request Part A: (BASIC)
To verify an IKEv2 device ignores the content of RESERVED filed in IKE messages.
* [RFC 4306] - Sections 2.5
* 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.

All RESERVED fields are set to one.
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. TN1 transmits a CREATE_CHILD_SA request including a Notify Payload of type REKEY_SA and rekeyed CHILD_SA's SPI value in the SPI field to the 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 a CREATE_CHILD_SA response including "ENCR_3DES", "AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as proposed algorithms.
* None.
