     association setup MUST be aborted.

  4.6.2 Identification Payload Content


   The Identification Payload is used to identify the initiator of the
   Security Association.  The identity of the initiator SHOULD be used
   by the responder to determine the correct host system security policy
   requirement for the association.  For example, a host might choose to
   require authentication and integrity without confidentiality (AH)
   from a certain set of IP addresses and full authentication with
   confidentiality (ESP) from another range of IP addresses.  The
   Identification Payload provides information that can be used by the
   responder to make this decision.


   During Phase I negotiations, the ID port and protocol fields MUST be
   set to zero or to UDP port 500.  If an implementation receives any
   other values, this MUST be treated as an error and the security
   association setup MUST be aborted.  This event SHOULD be auditable.


   The following diagram illustrates the content of the Identification
   Payload.
