The NUT transmits an Echo Reply with IPsec ESP using corresponding algorithms.
Step 72: Judgment #4
The NUT transmits a CREATE_CHILD_SA request including properly formatted TSr
Payload containing following values:
1 2 3

* A Critical field is set to zero.
* A RESERVED field is set to zero.
* A Payload Length field is set to length of the current payload.

* A TS Type set to TS_IPV6_ADDR_RANGE (8).
* An IP Protocol ID field is set to zero.
* A Selector Length field is set to length of this Traffic Selector Substructure
including the header. It is 40 bytes for TS_IPV6_ADDR_RANGE.
* A Start Port field is set to zero.
* An End Port field is set to 65535.
* A Starting Address field is set to less than or equal to TN1 address.
* A Starting Address field is set to less than or equal to TN1 address.
* The implementation may use different SA lifetimes by the implementation policy. In
that case, the tester must change the expiration time to wait CREATE_CHILD_SA
request.
* CREATE_CHILD_SA request has following packet format.It may have additional
payloads described below. Additional payloads can be ignored by this test. The order of
payload may be different from this sample.

[N(IPCOMP_SUPPORTED)+],
[N(USE_TRANSPORT_MODE)],
[N(ESP_TFC_PADDING_NOT_SUPPORTED)],
[N(NON_FIRST_FRAGMENTS_ALSO)],

* The implementation may not set single proposal by the implementation policy. In this
case, Security Association Payload contains multiple proposals.
* Each of transforms can be located in the any order.
* The implementation may not set single traffic selector by the implementation policy. In
this case, Traffic Selector Payload contains multiple proposals.
