Test IKEv2.EN.I.1.1.3.6: Sending Delete Payload for IKE_SA
Part A: (BASIC)
To verify an IKEv2 device transmits 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.
In addition, set IKE_SA Lifetime to 60 seconds and set CHILD_SA Lifetime to 30
seconds.
* Pre-Sequence and Cleanup Sequence
IKEv2 on the NUT is disabled after each part.

Part A: (BASIC)
1. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request.
2. Observe the messages transmitted on Link A.
3. TN1 responds with an IKE_SA_INIT response to the NUT.
4. Observe the messages transmitted on Link A.
5. After reception of IKE_AUTH request from the NUT, TN1 responds with an IKE_AUTH
response to the NUT
6. TN1 waits until expiring IKE_SA's lifetime and does not respond to an INFORMATIONAL
request with an INFORMATIONAL response for liveness check.
7. Observe the messages transmitted on Link A.
Part A
Step 2: Judgment #1
The NUT transmits an IKE_SA_INIT request including "ENCR_3DES",
"PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96" and "D-H group 2" as proposed
algorithms.
Step 4: Judgment #2
The NUT transmits an IKE_AUTH request including "ENCR_3DES",
"AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as proposed algorithms.
Step 7: Judgment #3
The NUT transmits an INFORMATIONAL request with a Delete Payload including 1
(IKE_SA) as Protocol ID, zero as SPI Size and no SPI value.
* At Step 7, NUT can transmit INFORMATIONAL request with a Delete Payload
including 2 (ESP) as Protocol ID, 4 as SPI Size and SPI value to delete CHILD_SA
before transmitting an INFORMATIONAL request to delete IKE_SA.
