Test IKEv2.EN.R.1.1.3.4: Receiving Liveness check Part A: (BASIC)
To verify that an IKEv2 device can respond to INFORMATIONAL request for liveness check.
* [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.In addition, set IKE_SA Lifetime to 300 seconds and set CHILD_SA Lifetime to 30 seconds. * Pire-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. After reception of IKE_AUTH response from the NUT, TN1 transmits an INFORMATIONAL request with no payloads. 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 6: Judgment #3 The NUT transmits an INFORMATIONAL Response followed by an Encrypted payload with no payloads contained in it.
