Test IKEv2.EN.R.1.1.3.5: Receiving Delete Payload for IKE_SA Part A: (BASIC)
To verify an IKEv2 device can respond to INFORMATIONAL request with a Delete Payload, when IKE_SA is deleted.
* [RFC 4306] - Sections 2.4 and 3.11
* 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_AUTH response from the NUT, TN1 transmits an IKE_AUTH request to the NUT. 4. Observe the messages transmitted on Link A. 5. TN1 transmits an INFORMATIONAL request with a Delete payload including 1 (IKE_SA) as Protocol ID, zero as SPI Size and no SPI value. 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 7: Judgment #3 The NUT transmits an INFORMATIONAL response with no payloads.
* None.
