The IP Security Authentication Header (AH) and Encapsulating Security
Payload (ESP) protocols use a sequence number to detect replay.  This
document describes extensions to the Internet IP Security Domain of
Interpretation (DOI) for the Internet Security Association and Key
Management Protocol (ISAKMP).  These extensions support negotiation of
the use of traditional 32-bit sequence numbers or extended (64-bit)
sequence numbers (ESNs) for a particular AH or ESP security
association. 

This document is a product of the IP Security Protocol Working Group
of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
