Test IKEv2.EN.I.1.2.4.4: Sending Multiple Transform
Part D: Multiple D-H Groups (ADVANCED)
To verify an IKEv2 device properly transmits CREATE_CHILD_SA request with multiple
transforms to rekey IKE_SA.
* [RFC 4306] - Sections 2.8
* 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 60 seconds and set CHILD_SA Lifetime to 300
seconds.

Part D: Multiple D-H Groups (ADVANCED)
28. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request.
29. Observe the messages transmitted on Link A.
30. TN1 responds with an IKE_SA_INIT response to the NUT.
31. Observe the messages transmitted on Link A.
32. After reception of IKE_AUTH request from the NUT, TN1 responds with an IKE_AUTH
response to the NUT
33. TN1 transmits an Echo Request with IPsec ESP using corresponding algorithms to NUT.
34. Observe the messages transmitted on Link A.
35. Repeat Steps 6 and 7 until lifetime of SA is expired.
36. Observe the messages transmitted on Link A.
Part D
Step 29: 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 31: 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 34: Judgment #3
The NUT transmits an Echo Reply with IPsec ESP using corresponding algorithms.
Step 36: Judgment #4
The NUT transmits a CREATE_CHILD_SA request including
"ENCR_3DES","PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96", "D-H group 2" and
"D-H group 14" as proposed algorithms. And the CREATE_CHILD_SA request includes 1
(IKE) in the Protocol ID field, 8 in the SPI size field and rekeyed IKE_SA's SPI value in the
SPI field.
* Each NUT has the different lifetime of SA.
