| None | 0 | This type MUST be implemented. In this case, the size of the Rekey Event Data field will be zero bytes long. The purpose of a Rekey Event Payload with type None is when it is necessary to send out a new token with no rekey information. GSAKMP Rekey Msg requires a Rekey Event Payload, and in this instance it would have rekey data of type None. | [RFC4535] |
| GSAKMP_LKH | 1 | The rekey data will be of type LKH formatted according to GSAKMP. The format for this field is defined in Section 7.5.1.2 of [RFC4535]. | [RFC4535] |
