Test IKEv2.EN.I.1.1.3.3: Close connections when repeated attempts fail
Part A: (BASIC)
To verify an IKEv2 device stops retransmission when it receives the corresponding response.
* [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. 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. TN1 waits for the event of a timeout on the NUT.
6. Observe the messages transmitted on Link A.
7. Repeat Step 5 and Step 6 until the NUT's last restransmission comes.
8. 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 6: Judgment #3
The NUT retransmits an IKE_AUTH request which has the same Message ID value as the
previous IKE_AUTH request's Message ID value in IKE Header.
Step 8: Judgment #4
The NUT never retransmits an IKE_AUTH request which has the same Message ID value as
the previous IKE_AUTH request's Message ID value in IKE Header.
* None.
