Test IKEv2.EN.R.1.1.7.2: TS_UNACCEPTABLE
Part A (BASIC)
To verify an IKEv2 device properly handles the Traffice Selector.
* [RFC 4306] - Sections 2.8 and 3.10.1
* 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. TN1 starts to negotiate with NUT by sending IKE_SA_INIT request.
2. Observe the messages transmitted on Link A.
3. After a reception of IKE_SA_INIT response from the NUT, TN1 transmits 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
CREATE_CHILD_SA request including ICMPv6 (58) as IP Protocol ID value in Traffic
Selector Payload to create new CHILD_SA.
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 does not transmits a CREATE_CHILD_SA response or transmits a
CREATE_CHILD_SA response including a Notify payload of type TS_UNACCEPTABLE.
* None.
