3.2.7.1 Enumerator Finishes Enumerating Responders

After the Enumerator role is fulfilled (that is, when the Block timer is stopped, as specified in section 3.1.6.1), an entry in the Network Topology Test Session List MUST be created for each responder that is discovered. The Sequence Number field MUST be initialized to a nonzero number (by means of any random number generator). All subsequent requests with a nonzero sequence number that the mapper sends MUST adhere to the defined sequence numbering rule. The Pended Request field for the initialized entry MUST be empty.

At this point, the mapper MUST indicate to the application or higher-layer protocol that it is ready to perform network topology tests.
