Test IKEv2.EN.I.1.1.6.1: Cryptographic Algorithm Negotiation for IKE_SA
Part B: Encryption Algorithm ENCR_AES_CTR (ADVANCED)
To verify an IKEv2 device properly handles the Initial Exchanges using Pre-Shared key.
* [RFC 4306] - Sections 2.7 and 3.3
* Network Topology
Connect the devices according to the Common Topology.
* Configuration
From part A to part E, configure the devices according to the Common
Configuration except for Italic parameters.

5. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request.
6. Observe the messages transmitted on Link A.
7. TN1 responds with an IKE_SA_INIT response to the NUT.
8. Observe the messages transmitted on Link A.
Part A
Step 2: Judgment #1
The NUT transmits an IKE_SA_INIT request including "ENCR_AES_CBC",
"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 which is cryptographically protected by the
proposed algorithms in Step 1.
* None.
