Technical Summary The IPsec Authentication Header (AH) and Encapsulating Security Payload (ESP) protocols use a sequence number to detect replay. This document describes extensions to the IPsec DOI for ISAKMP. These extensions support negotiation of the use of traditional 32-bit sequence numbers or extended 64-bit sequence numbers for a particular AH or ESP security association. Working Group Summary The IPsec Working Group came to consensus on this document. Protocol Quality This document was reviewed by Russell Housley for the IESG.
