Test IKEv2.EN.I.1.1.3.1: State Synchronization with ICMP messages
Part A: (BASIC)
To verify an IKEv2 device synchronizes its state when it receives ICMP messages.
* [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. After reception of IKE_AUTH request from the NUT, TN1 responds with an IKE_AUTH
response to the NUT
6. TN1 transmits an Echo Request with IPsec ESP using corresponding algorithms to NUT.
7. Observe the messages transmitted on Link A.
8. After reception of an Echo Reply from NUT, TR1 transmits ICMP Destination Unreachable
Message to the NUT and then TN1 transmits an Echo Request to the NUT.
9. 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 Echo Reply with IPsec ESP using corresponding algorithms.
Step 9: Judgment #4
The NUT transmits an Echo Reply with IPsec ESP using corresponding algorithms.
* None.
