Title

  Test IKEv2.EN.R.1.2.6.5: Receiving Multiple Transform
  Part D:


Purpose

  To verify an IKEv2 device properly handles a CREATE_CHILD_SA request with multiple
  transform to rekey IKE_SA.


References

  * [RFC 4306] - Sections 2.7, 2.8 and 3.3


Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the Common Configuration.
  * Pre-Sequence and Cleanup Sequence
      IKEv2 on the NUT is disabled after each part.
