Test IKEv2.EN.R.1.1.8.3: INVALID_SELECTORS Part A (BASIC)
To verify an IKEv2 device properly handles an ESP or AH packet whose selectors do not match those of the CHILD_SA.
* [RFC 4306] - Sections 3.10.1 * [RFC 4307] - Sections 7.8
* Network Topology Connect the devices according to the Common Topology. * Configuration In each part, configure the devices according to the Common Configuration except Traffic Selector. Traffic Selector should be configured as following.

Part A (BASIC) 1. TN starts to negotiate with NUT by sending IKE_SA_INIT request. 2. Observe the messages transmitted on Link A. 3. After reception of IKE_SA_INIT response from the NUT, TN transmits an IKE_AUTH request as the above table to the NUT. 4. Observe the messages transmitted on Link A. 5. After reception of IKE_AUTH response from the NUT, TN1 transmits an Echo Request with IPsec ESP using corresponding algorithms to NUT. 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 request with a Notify of type INVALID_SELECTORS.
* None.
